Aside from some things you would normally have around the house, like towels! ('cuz you'll really sweat!), here's a list of necessary and optional equipment:
Necessary:
A variety of dumbbells (you may have to get heavier ones than you now have! I added an extra 30#--I already had one--to my collection)
A yoga mat or surface on which to do yoga
A surface for doing plyometrics. I have puzzle mats over a wood floor, but I also bought the yoga mat they're selling, that is thicker than regular yoga mats and adds extra cushioning.
Optional:
Resistance bands (for pull-downs or as a variation for dumbbell exercises)
A pull-up tower or door bar (I consider these optional in the beginning, because I just did heavy 1-arm rows and pullovers instead of the pull-ups and chin-ups when I first started. If you want to do exactly what they are doing on the DVD, then either a resistance band with a door attachment that lets you attach it at the top of the door (the attachment that Beach Body sells with their bands is too risky, IMO, to be used that way. I bought an excellent (actually, two!) door attachment that has a large foam roller that stays on the opposite side of the door, from
www.sissel-online.com or sisel? ), or the pull-up bar or tower.
Push-up handles (you can also use a pair of dumbbells. If doing lots and lots of push-ups is new to you, these may help your wrists).
I think that's all!
My own special add-ons: (Not at all necessary, nor even shown in the workouts, but they helped me up the intensity of some of the work after a while, and gave me some variety and a sense of "play"):
medicine ball (to add to AbRipper X when it becomes easier, and to hold and toss and manipulate during the plyo workout--I used just 2 or 3#).
A balance disc (air-filled pad): I used these when the on-the-toes versions of push-ups were tough (after several sets), but the on-the-knees push-ups seemed too much easier. I put one knee on a balance disc, and held my other leg up behind me to do a "one-knee" push-up with a bit of added instability to work the core and add challenge.
