Instructions:
1) MAX push-up can be anything from 1 to 50. 1 rep is a legitimate rep.
2) All types of push-ups are accepted in this challenge: wall push-ups, knee push-ups, decline and incline push-ups, more challenging variations etc.
Extra Credit: Hold a push-up plank instead of a regular plank.
A combination of isometric and isotonic exercises is one of the best ways to build muscle, increase strength and improve joint stability. The Power Hold Challenge is the perfect vehicle to reap the benefits of this potent combination, over 30 days.
