You know that electric feeling you get after a killer workout? Yeah, times that by 10 and that pretty much sums up this past weekend for me!

If you haven’t heard, Saturday I teamed up with Lee {from Fit Foodie Finds}, The Her Initiative, and a bunch of local Minneapolis ladies {and a handful of ladies who traveled all the way from Chicago} for the #partyforhermpls! The day went a little like this — DJ Omaur Bliss was pumping jams as I led a leg-burning barre + HIIT workout and Lisa {from the I am Initiative} cooled us down. Then Kayla {from The Her Initiative} told us all about Her and the #25for25 program.

Did you know that 443 million school days are lost each year due to water-related diseases? And girls under the age of 15 are twice as likely as boys to be the family member responsible for fetching water? And if you give 82 cents a day to The Her Initiative, in one year you’ll give clean water, health and hygiene education to 25 women and children. If you weren’t able to make the event but still want to support The Her Initiative, empowering women with clean water, health and hygiene education you can donate here

After the workout and fun facts, we enjoyed lots of delicious Peace Coffee, Seven Sunday’s Muesli parfaits and Fit Foodie Finds Amazing Peanut Butter Balls while we shopped local MN makers and small, women-owned businesses.

But the best part of the whole day…well it’s a toss up between:

  • being surrounded by 70+ amazing, supportive women jumping at the opportunity to be part of a movement bigger than any single one of us in the room.
  • raising over $3k for the her initiative!!!
  • the connections that were made between like-minded women and business owners.

Clearly it was an overwhelming success! I can’t say thank you enough to everyone who showed up and played a roll in making this happen {The Real Food RDs, Lissadee Photography, Bee + Co. to name a few}!

So speaking of killer workouts and endorphins. Let’s jump into to this abs of steel medicine ball workout! What are you waiting for? You’re just 390 reps away from sculpting a tighter torso and flatter abs!

the workout: 390 reps, abs of steel medicine ball workout

1 medicine ball, 8 exercise x 2 sets for a total of 390 reps! Complete the number of reps listed next to each exercise below. Then repeat the entire workout x 2 sets for a total of 390 reps. Incorporate this 15 minute routine into your cardio and strength training to carve out your midsection.

A weighted, medicine ball is a great piece of equipment to use when training your abs because it challenges your core stability. I recommend using a medium-to-heavy medicine ball for this workout {5-to-15 lbs}.
