I just finished my first cross training workout using Max Capacity Training (MCT) on my phone. It is really easy to use and very effective. It certainly kicked my butt.
My first round scores were (reps in 50s):
Squats - 19
Push-ups - 19
Lunges - 18
Plank - 1 (held is for the full 50s)
I didn't score nearly as well in the other 3 rounds.
