Plank Skater Hops
To do Plank Skater Hops, start in a bulldog position from your hands and toes with your knees bent to about 90 degrees and feet together behind you. Straighten one leg out to the side and slight back, touching the toe down. You may even slightly shift the other foot more center under your body as you reach the straight leg out to the side.
Then hop that straight leg back in, bending it as you do, as you hop the other leg out laterally. You will almost be shuffling back and forth laterally while in the plank position. Keep your hands under your shoulders as you do. Your butt shouldn’t be way up in the air as you shuffle/hop side to side. You may “bounce” but your butt shouldn’t be up in the air.
Beginners may do less of a hop and move more slowly while advanced exercisers should hop quickly side to side. Remember to keep one knee bent under your body as the other leg goes out to the side. The straight leg will be out to the side and slightly back as you hop back and forth.
