In order to continue to build muscle, stay stronger and feel fit, you have to implement progressive overload into your strength training routine.

Most people think that means you have to lift heavier and heavier. While increasing the weights you’re using is a great way to challenge yourself, there are many other ways you can implement progressive overload into your leg day workout.

You can increase the number of reps or sets you complete, increase time under tension, or decrease rest periods.

Day seven of our 2-Week Perform 20 Dumbbell Workout Plan is made up of a variety leg exercises at home using dumbbells.

Short rest periods, isometric holds and increased time under tension throughout this performance-based strength workout will challenge your strength, stability and endurance.

I recommend warming up with hip mobility exercises to improve range of motion and make your squats and lunges more effective.

I suggest doing this leg workout once a week as part of a well-rounded workout routine.

  2. Hinge at the hips, pushing your hips back towards the wall behind you as you glide the dumbbell hand down the front of your legs, keeping your core tight, slightly bending both knees. Lower your dumbbells until you feel a stretch in the hamstrings. Range of motion will look different for everyone.
  3. Drive through the heels to push your hips forward, pulling the dumbbells back up towards your hip as you stand tall, returning to starting position.

6. Curtsy Lunge

Targets: Legs, quads (thighs) and gluteus maximus (butt), hip flexors and core.

How To Do A Lateral Lunge

  1. Start standing, feet hip-width apart, slightly bent knees. Hold one dumbbell in your left hand.
  2. Step your right leg out to the side as you push your hips back, bending your right knee while leaving your left leg straight. Think of performing a single leg squat with your right leg while your left leg remains straight. Knees and toes are pointing forward.

How To Do Dumbbell Swings

  1. Stand with your feet wider than shoulder-width apart, holding a single dumbbell vertically between your hands.
  2. With a slight bend in your knees and weight in your heels, ‘hike’ the dumbbell back between your legs to start the swing movement.
  3. Drive through your heels to stand tall, pushing your hips forward as you squeeze your glutes to swing the dumbbell up. Aim for shoulder height, with arms extended out away from the body. Think long, loose arms (your arms are just a vehicle for moving the weight, your hips and glutes generate the power).
  4. As the dumbbell begins to descend, think of catching the weight with a hip hinge, loading the glutes and hamstrings.
How Heavy Should My Dumbbells Be For A Leg Workout?

I would suggest that you use heavier dumbbells for leg workouts than you do for arm workouts. But how heavy your weights are depends on your fitness level. Beginners may want to start with around 10% of their bodyweight, and increase weight as you get stronger or become more advanced in form and technique. Another great measurement is the last 2-3 reps of each exercise should feel challenging to complete with good form.

What If I Don’t Have Dumbbells At Home?

You can perform this entire leg workout with just your bodyweight or look for various household items that you might be able to use as weights. Good dumbbell substitutions included: filled water bottles, laundry detergent containers, gallon jugs of milk or juice, or a backpack filled with books.

What Are Good Dumbbell Leg Exercises To Train The Legs To Failure?

Squats are one of the most effective compound lower body exercises that targets the quad muscles, glutes, hamstrings, and core. However, a well-rounded leg day workout will also include a variety of movement patterns, such as deadlifts, lunges, and hip thrusts/glute bridges. Keep in mind that your legs are a large muscle group, so you should lift heavy in order to train them to failure.
