Who wants to push-up?! Try this out first!
1) Start in quadruped to find the right shoulder/arm/wrist alignment.
2) Step back with one foot, dig in the toes and push back into the heel.
3) Keep the tension through your heel as you step back with your bent leg.
4) Pause, maintain your plank, then bring your other knee up until your knee cap passes your waist.
5) Pause, repeat, keeping the hips level.
