Anybody use these with p90x? I have dumbbells but only up to 35lbs and its a pain to carry them to the top floor from the basement to workout.(basement ceiling is to low to do a lot of exercises) Mixed reviews. Some say good some say bad. Here is the super kit. 20-40 pounds.
this is the extreme kit. 40-50 pounds.
The dumbbells i have are 10,20,25,35
Any input is greatly appreciated Ian.
