Power 90 Extreme

Power 90 Extreme, or P90X for short, is a rigorous - and can I say, downright merciless - workout plan that stretches over 90 days in three 30-day periods. Like many training methods, P90X focuses on cardiovascular, strength, and stretching exercises.

Twelve forms of workouts are included in the P90X plan:

1. Chest and Back
2. Plyometrics (nervous system)
3. Shoulder and Arms
4. Yoga X
5. Legs and Back
6. Kenpō X (form of martial arts)
7. X Stretch
8. Core Syngergistics
9. Chest, Shoulders, and Triceps
10. Back and Biceps
11. Cardio X
12. Ab Ripper X

Just to clarify, the "X" merely stands for an over-the-top version of the workout. For the most part, each session lasts about an hour. That's only ideally, though, since time used to warm up and cool down are factored in, as well as extra time for those who cannot fully keep up with the workout (pause button is amazing).

Only three days in and this is the first time I've felt overwhelmingly sore since my high school fencing team's hell-week in freshman year. In other words, it has been a whopping six years since I pushed myself this much. 87 more days to go through cycling these workouts.
