This is a really intense 21 day challenge that pushes your fitness limits.
I had to add a few recovery days in between each week, but am much stronger and more flexible at day 18.
Amazing trainer!
The whole challenge is great! You really exercise until the last minute of the routines. Jake does a variety of exercises that are fun and challenging so they keep you engaged. He also explains the correct form while performing the exercises. This has made all the difference in my routines.
