The great part about the P90X program is that you really don't need much in the way of equipment.
You'll need the following:
- A pull-up bar. Beachbody sells one that you can buy when you purchase the program. It's nice, but you have to have traditional door frames/mouldings for it to mount. I have it but I also purchased a full-blown pullup station with power assist because when I started I had real trouble with the pull-ups and form. See below in the "optional" section.
- Dumbbells or bands. If you don't have space/money for dumbbells or the ability to mount a pullup bar, you use the bands in substitution AND they take the place of dumbbells, also. You can purchase bands from Beachbody or (see below) from other sources. The dumbbells can be the traditional individual weighted units or (see below) what I got -- the Bowflex Selecttech modular units which take up MUCH less space.
- A Chair or stool. You'll need this for some of the plyo moves, some general balance and the seated exercises/inverted pushups, etc.
- A towel
- A Pen
- A water bottle
- A DVD Player
I'll save the motivational "you need commitment!" line item...
- Pullup station with assist to get max. reps with good form. I started with the power assist and now I'm weaning off it since I'm strong enough to do at least 10-15 of each type of pullup now. I got this one from Sports Authority. it's a dip/ab/pullup power tower that works nicely. You might also consider the Perfect Pullup since it allows for inverted rows, doesn't need moulding to hang and allows for a greater range of motion/exercises.
- Selecttech dummbells. These are great. I got the 552 which allows you to dial up to 52 pounds in a single, consolidated stack. Saves SO much space. They are a little more bulky so some of the exercises require some extra strict form, but I love these things. Got my Nautilus-branded ones at Costco for $349.
- Modular Bands. My buddy George turned me on to these. These bands (although they have TO's name on them) look great. The mounting options are very nice, the modularity of being able to "stack" weight is a bonus. You can take these with you when you travel, so you don't have to miss a workout.
- Pushup bars. For those of you with weak wrists or a desire for greater range of motion, pushup bars are great. I went a little different route and use the Perfect Pushup which adds additional fun to the pushup routines, helps my wrists (which are sore from BJJ) and helps isolate the chest workout more. I believe BB sells more standard units or you can also use dumbbells for the same purpose.
- Supplements and recovery drinks. I take a bunch of supplements already, so I'm not going to recommend any because I'm not a physician. I know what works for me. I will, however, tell you that the P90X recovery drink (or one like it) is very good for post-workouts and I regularly consume Muscle Milk chocolate shakes and Fast Twitch drinks prior to working out. More on these later.
Hope these were helpful.
