OPro helps you with the complicated calculations involved in following Occam's Protocol for massive weight gain. This protocol was recently rediscovered when it was featured in Tim Ferriss's book "The 4 Hour Body".

Occam's Protocol is a strategy for gaining large amounts of muscle mass over a short period of time. It involves doing very precisely calculated weights, with high intensity, at a precise cadence, on a precise schedule.

The hardest parts of following Occam's Protocol are:
- determining your starting weights,
- determining when your next workout should be scheduled, and
- determining what weights to use for your next workout.
OPro takes care of all that for you.

OPro has a wizard to walk you through the process of finding out your starting weights.

Determining the date of the next workout can get very tricky once you take into account stalls and failed workouts. OPro will figure the scheduling out for you.

In addition, OPro helps you with the timing of each exercise and the timing between exercises.
