what does situps have to do with jumping?? Jumping is a total body, totally integrated movement skill that does not smell anything like a situp.
Training the trunk to jump starts on you feet and ends there. Resistance band training is the perfect way to get reacting.
Wow! Nobody gets more bang for the buck out of bands than Dave "The Band Man"
