For Robert's Birthday Challenge, he created exercises that will test his stamina, flexibility, and a bunch of other aspects of his fitness, but it's mainly designed to test the strength of his right knee that he injured 8 months ago.
For your Birthday Challenge, you can do his exercises, or you can create your own.
Unsure of what you want your challenge to be? No worries. Click here to sign up for a free Birthday Challenge Assessment, and discuss it with Robert.
