I was thinking about starting Insanity. I used to work out pretty religiously throughout my 20's but have really lapsed over the past couple of years. My last dedicated routine was P90X about 2.5 years ago.
How much space do you need for this? I can pretty comfortably do the plyo routine from P90X in my living room space - would that be enough? Also, do you need anything in terms of equipment? One of the main reasons I don't want to do P90X again is that I'd rather not have to keep the weights and floor mat sitting around, etc.
