Strengthen and sculpt the upper abs, lower abs, obliques, glutes and six-pack muscles with this free, 30-day ab challenge. This cohesive program includes a variety of bodyweight and weighted ab workouts designed to build stability in the core in around ten minutes a day. Each of the daily core workouts includes beginner and advanced modifications.
Build a stronger core at home in around ten minutes a day with this 30 day ab challenge.
This ab challenge is designed specifically for busy women like you – whether you’re a mom juggling it all, managing a career, or simply want to prioritize your fitness. Time is precious, so this plan is not only effective but also doable within your busy schedule.
Forget the pressure of achieving a “six-pack” (though a stronger core is a great side effect!). This challenge focuses on functional fitness, meaning the exercises you’ll do will translate directly into everyday life. You can make everything from carrying groceries to chasing after the kids to crushing your next full body strength workout easier.
The best 30-day workout challenge for abs isn’t just about crunches. This plan includes both bodyweight and dumbbell core exercises that activate your deep core muscles, like planks, dead bugs, mountain climbers and leg raises.
This plan is progressive, so we’ll gradually increase the intensity and complexity of the ab workouts as your core gets stronger. We’ll start with foundational, bodyweight movements that focus on proper form and engaging the right muscles.
Then, we’ll progress to more challenging, weighted abs exercises that target different areas of your core – the obliques, the rectus abdominis, and the transverse abdominis (your deepest core muscle). Complete as many reps as you can within the timed interval, always prioritizing form over speed.
After 30 days of dedicated core training, you’ll notice a difference. Don’t be surprised if you feel muscles you never knew you had! Rest is just as important as the workouts themselves, so be sure to focus on form and recovery.

These ab workouts can be done with just your bodyweight. Some workouts include optional equipment:
Dumbbells (Discount Code: NML). Each workout will have a recommended dumbbell weight, usually between 5-15 pounds.
Kettlebell (Discount Code: NML). Option to substitute one heavy dumbbell instead.
Mini Loop Resistance Band (Discount Code: NML)
Varies from 5-15 minutes a day, 7 days per week.
For the best results, I recommend adding this ab challenge onto another strength training workout plan.
Appropriate for all fitness levels. The daily workout videos do offer exercise variations, modifications and options to increase the intensity as well.
Free! No sign up needed, this is a free workout plan.
You’ll certainly notice a stronger core if you do an ab workout every day. That said, your abs need time to rest and rebuild after a workout, just like any other muscle group. Pay attention to how your body feels, and incorporate rest days as you need to. I recommend using a variety of exercises targeting different abdominal muscles (upper, lower, obliques) to avoid overworking specific areas. You can also incorporate full body and abs, as well as arms and abs workouts into your routine.
For the best results, pair a 30-day ab challenge with a split training workout plan and a high-protein meal plan. Focus on lean protein sources, as protein is essential for muscle repair and growth, which can help define your abdominal muscles.
In order to see a flat belly or defined abs, you need to reduce overall body fat and belly fat. This takes time and requires targeted exercises that strengthen the core, as well as eating in a calorie deficit. Focus on a balanced diet with plenty of fruits, vegetables and lean protein, and incorporate regular cardio HIIT workouts to burn calories and promote overall fat loss.

I so appreciated this workout I just finished day four. I hurt my back after being sick in bed for 4 days and this workout is helping me get back on track with working out and my whole body just feels looser. And even emotionally I feel happier. I am not yet able to use 15 lb weights. But I will do it again and try to load up more next time. I appreciate having a program where I don’t have to think about what to do next. Thank you so much Lindsay and the NML team.
Love these workouts. I’m not a fan of weight training, counting reps and sets as I find this tedious. Love that these are 30-50 seconds of work which if I chose the correct weight brought me to failure. These workouts are never boring and the 20 minutes goes by so fast. I’m definitely seeing results after doing the entire Strong20 4 times. I’m moving on to Stronger25. Thank you so much Lindsay! Ps I also love that you have devotionals, I just found them and will definitely be using those too. God Bless you and keep you Lindsay.
I loved the 20 minute workouts. They fit well into my schedule during the school year having less free time. I felt challenged and like I was able to build muscle with the repeated, challenging exercises. I also liked the mobility in a longer warmup. And, as always, the education during the workouts is appreciated and valuable. Thanks for another great program!
I’m now heading into my third trimester and have been following the 1st and 2nd workouts from this pregnancy program, and I absolutely love them. What I appreciate most is the variety. There’s a workout to match whatever mood I’m in that day, with different lengths and different styles to choose from. It makes it so much easier to stay consistent throughout pregnancy. I cannot thank you enough for this!
I had been feeling burnt out with recent workouts and needed a change. I recently completed the Strong 20 program and it was so fun, yet challenging. I loved that I could fit it into my busy schedule as a full-time working mom of 3. I am going to start the Stronger 25 next. Love your positivity and the pace of the workouts!
I cannot describe how grateful I am to have found these postpartum workouts. I not only feel like I have found a trainer, but a much-needed tribe member on the other side of the screen.
I really appreciate Lindsey’s dedication and how she brings her real self to each workout, since being a mom of three small kids can feel so lonely. She is great company and makes it much easier. Thank you!
I have been really enjoying Max 20! Unfortunately joining the app to access the additional week of workouts isn’t in my budget at the moment, but I love the 10 days that are available for free. I am on my 4th week(day 7) of doing this program and I can see myself repeating the 10 day program throughout the summer. My strength has improved since beginning this program on 6/1 and I would even say this is my favorite NML program I’ve tried so far.
Response from Nourish, Move, Love
Thank you for sweating with us! We’re so glad you’re enjoying Max 20. Keep up the great work!!
I am 64 and still working so it has been hard to get to the gym. I love these short,effective workouts and modifications. My adult daughter is following along and we send each other sweaty selfies to encourage each other haha. Thank you so much for providing this resource for free Lindsey.
This is the first program I’ve been excited to complete in a long time! I was feeling burnt out by weight training and needed something different for little bit that’s also effective. This is perfect! I notice my range of motion improving and it also provides a good refresher on proper form without the added weights. I love Lindsey’s enthusiasm and that my young daughter hears her encouragement and joins me and cheers me on. I’m excited to dive into her other programs as well!
I want to sincerely thank you, Lindsey Bromgren, from the bottom of my heart for all the content you create.
I’m here to express how grateful I am for your work. Before I found you, I was already training, but I felt like I was missing something more structured and motivating for this phase of my life.
I had been training intensely before pregnancy, but during pregnancy I reduced the intensity. Now, in the postpartum period, I’m getting back into it with full commitment.
I found you about 1 month and 2 weeks ago, and I’m about to complete 3 weeks in your postpartum program. I’m already repeating the program for the second time, so technically I’m in my third week — and I’m also combining it with your diastasis program.
It has been an incredible experience.
During this time, I’ve already lost 22 lbs out of the 35 lbs I gained during pregnancy, just 4 months postpartum, and I’m almost back to my pre-pregnancy weight.
More importantly, training with your program has been extremely motivating and consistent for me. I feel stronger, more confident, and very supported throughout this journey.
Thank you so much — I truly needed to express my gratitude for this.
I am getting back into shape! I am premenopausal, overweight, and lazy. And you inspired me to move. I just started the 30-day beginner workout in conjunction with a good diet and walking workout. I am feeling great and can’t wait for more!
I was unsure where to start in my workout journey at 6 weeks postpartum with my second baby. I did not prioritize exercise after having my first baby just 2.5 years ago so I knew I needed a specific program for postpartum. It has helped me so much! I feel so much stronger and confident. I plan on continuing a new NML program next!
Lindsey is a great instructor. She has great energy and has great workout plans. I love how she keeps it real, she doesn’t pretend to be perfect and lets you know when she is feeling the burn and struggles right along with you. Her co-instructors are wonderful too. I love how they do the modified version of the exercise, which is the version I have to use about half the time.
Day 2 arm day! Wow! Seemed easy when I started and now my arms are burning. Grateful for a good 20 mins!
I have been doing NML workouts for over a year now and find the variety and time limit very doable for this extremely busy time in my life. As someone who has done every single program NML has, getting a new one in time for summer is a dream.
I love this program and the ease of turning on the tv and getting it done. I love that Lindsey is encouraging, knowledgeable, and has put together such a well thought out plan. I’ve been going for a few months and I’ve really seen improvements . Thank you NML!
I love these short effective workouts. I’m older(56) and longer workouts are very challenging for me. But Max 20 is exactly what I need and love. Going heavy and building strength. All part of my nursing home prevention program and I love you are a part of it too.
I started weight training again in January after taking a break due to life and I’m so glad I came back to what got me going again. I’ve loved these workouts for years and after doing this program I have never felt stronger. I’m on my 2nd go and I already feel the gains and can’t wait to try increasing weight ❤️.
Over 70 mom and grandmother, who is trying to set an example for the next generation. Love ths workout my goal is a real pull up in 6 months and better muscle definition. It takes longer for senior but it’s possible. Thanks Lindsey andz Rachel
I was looking for an injury friendly workout. As someone who enjoys HIIT training, I had to step away from this style due to a tear in my hip labrum. I wanted to work on muscle building while giving the high impact a rest. After completing this workout for 4 weeks, I noticed muscle strength by bringing them to fatigue (lower weight/higher reps) and surprisingly my VO2Max also increased. I can only attribute it to the 2 min hiit finishers. I love the adding this on the end, getting my hiit fix/my HR high but also preserving my injury. Do Not underestimate this style of workout. I was very impressed with this program!
I started Overload 30 back in November 2025 and went through it 1.5 times before the holidays; took me about 3 weeks. Travelled, took some time off, then started it again. Did Overload 30 3 times over 1.5 months and I feel AWESOME! Had to do some of the modified moves, but I finished!! Thanks Lindsey and Rachel, you gals are great!
Seven months ago, I had open-heart surgery to replace my aortic valve. My sternum was literally cut open and bound together with wire. After eight weeks, my movement and lifting restrictions were lifted, and I was off heavy pain meds, unable to start driving and back to life with five kids. I completed cardiac rehab rehabilitation, but I had not lifted more than 5 pounds the entire time. I was a long way to go to recovery and regain my strength. A friend recommended this program and I started on it and was able to do a few days in a row and then rest for a few days but I was able to do it. I started out at 5 pounds and then increased to eight and then 10 and then 12 pounds. I’m about to finish the program tomorrow and I’m so much stronger and more capable. I also am able to do walks and runs and longer cardio exercises and yoga. This is absolutely changed my life for the better. Thank you!
Great program! I really like how this athlete-style workout combines strength training with mobility, balance, and conditioning—it makes the routine more functional rather than just focused on aesthetics. The use of trisets, HIIT intervals, and progressive overload is a smart way to improve both muscle and athletic performance over time. Training 25–30 minutes a day with a structured plan like this is practical and sustainable for long-term results
Absolutely love this 4 day workout split!! It’s challenging but doable and I feel so strong after completing it!! Please do more videos like these, especially with the rep drops!
I’ve been doing a different plan for the last year on repeat, had some good results. Injured my knee and recovered and tried to get back into that program, but it felt boring. Found this one, and the muscle gains have been incredible. Symmetry in my legs is almost if not fully equal now, my arms are more defined than they’ve ever been, and I always feel great after I finish the workout. They are fun and encouraging to work out with as well. Definitely recommend!

Hi team! I love all the workouts!! Can you please tell me the best workouts to target the lower stomach? Thank you for your help 🙂
Emily
Hi Emily! So glad you’re loving the workouts! We have a couple “lower abs” workouts on our site – search for that term and they’ll pop up. Those are great options! -Lindsey
