Just bought TUFF CUFF, where do i start?

I just recieved the tuff cuff program and i was wondering where i start. I looked at the calender and it says during May i should be on phase 5. So should i start on phase 5 since it is perscribed for May or should i just start on phase 1 and progress from there? If anyone could answer this or point me in the right direction that would be great.

Start at phase 1, next year you’ll be on calender.

Phase 5 is the phase to do during your season. So if you are currently in baseball season (playing games), do phase 5 until the season ends. If you are not currently in season, do whatever TUFFCUFF tells you to (Phase 1 if you are a HS pitcher).
