This drill is for working the absolute end range of your punch or jump. You can see that the ankle remains extended throughout and that the power for the push is coming from only the extension of the toes. The band is for both resistance, and the return to the mat to keep the reps moving (essentially acting in place of gravity since we are pressing horizontally). Lots of athletes simply push a little and expect loads of power, this simple drill can help them understand there is power left unused if you quit extending before pushing all the way through your toe extension and not just ankles.
This one was a Tammy Biggs special! Thanks Tammy!
Hope this helps you and your athletes create their Best Darn Gymnastics!
