Who It's For / Not For

Good fit: Intermediate exercisers, self-motivated, 60–90 min/day available, minimal equipment (bands, dumbbells, pull-up bar).
Not ideal: Absolute beginners, significant joint issues, time-crunched (<45 min), prefer gym community.

Progression & Modifications

• Modify plyometrics (low-impact versions).
• Use bands instead of weights initially.
• Follow calendar; don't skip recovery weeks.
• P90X2/3 offer more functional/athletic progression.

Real Talk

P90X works if you show up. It's hard. You'll be sore. You'll want to quit. The ones who finish change their relationship with effort. That's the real product.
