Sumo squats target your quads and inner thighs especially, but Melissa said they also work your glutes, hamstrings, and hip flexors, and the crunches work your obliques and your rectus abdominis, or six-pack muscles.
- Stand with your feet shoulder-width apart and feet slightly pointing outward.
- Place your hands behind your head with your elbows out wide.
- Keeping your core tight and weight on your heels, push your butt back as you bend your knees and lower down. Return to standing and bring your right elbow to your left knee, crunching across your body.
- As you open up, lower back down into a squat, then return to standing and crunch the opposite elbow to the opposite knee.
- Continue squatting and alternating crunches for 30 seconds.
