2 Moves to A Flat Belly

You don’t need a complicated routine to target your abs. There’s no need for fancy equipment or a hundred variations of the crunch. In fact, these two flat belly moves can fit in before or after your workout might be more effective in the long run.

This 2-move routine is the perfect easy ab workout: a straight-leg jackknife crunch to target your upper and lower abs, and a weighted Russian twist for your obliques and transverse abdominals. This workout uses intervals to maximize calorie burn and fat loss. Working to reduce the amount of fat in your body will help give you a lean and defined core.

What You’ll Need: Interval Timer (Gymboss is a free to download app), medium weight (8 – 15 lb.), gym mat or towel to lay on the floor

What to Do: Set your interval timer for 40 seconds of exercise and 20 seconds of rest. Alternate through the exercises until you complete the assigned number of sets for each move.

Beginner: 3 sets
Intermediate: 5 sets
Advanced: 7 sets

Below, we’ve included videos on how to perform the exercises with proper form. Using proper form can prevents injuries and helps ensure you get the most out of your workout.
