Week 15: 1000 Chain Punch Challenge

How are your shoulders feeling? probably not that bad by now ;)

chain punch as hard as you can for 30 seconds, followed by 20 second rest. Repeat this 20 times.

Follow up with vertical fist push ups (with fist protectors or not) 4 sets of 10 reps.

Followed with forward step, alternating legs, for 10 minutes.

Good luck ;)
