The Ab Slide: Variations
The Ab Slide is a great exercise to target your abdominals while also working the thighs and getting your heart rate up.
Get into a solid plank position with your Glutes and core engaged. Pull your knees towards your chest as you contract your abdominals and allow the spine to flex slightly. Push your feet back into the starting position. Do not allow your hips to sag as you push the feet back.
There are several variations of the Ab Slide. In addition to two legs simultaneous, you can do 1 leg at a time, alternating.
Or you can do a pike variation with the legs straight which is particularly challenging and really seems to engage the lower ab and obliques well.
