5 Moves to Strengthen Your Core

A strong core looks good on everyone! And having strong abdominal muscles can help in several aspects of your fitness life. Abs help you maintain proper posture while lifting, which prevents injuries, and they keep your body stable during planks, push-ups, and mountain climbers. These five core moves will help you tone and strengthen those abdominal muscles!

The reverse crunches target your lower abs, while sit ups target upper abs. Bicycle crunches and Russian twists will work both your obliques and transverse abdominals. The final move, the jackknife crunch, engages both upper and lower abs for a killer finish.

So go ahead and try these core moves for strong and defined abs. You can follow our workout, or integrate the exercise moves into your own routine.
