Stamina X 50-pound Versa-Bell Dumbbell
I bought these specifically for P90X and I am entering week 5 so I thought I would review these specifically for that program.
These are the cheapest adjustable dumbells you can buy anywhere. Use a 10% coupon. I think I got mine for ****. delivered. Can't beat that. Came in two boxes, everything shipped well.
These dumbells are adequate for P90X however the program requires you to adjust weight quite a bit on some of the sessions and the adjustment of the dumbells take longer than the program allows. You will be hitting the pause button at times. However the adjustment (which has to be done on both ends of the dumbbell) is easy and fluid. Returning the weights can sometimes take a bit a time especially if your using low weights to re-allign the weights into the handle. I have never had a feeling of any safety concerns with these dumbbells.
The weights are not balanced like real dumbbells on the odd weights (15, 25, 35, 45) but I have not found that to be to much of a hinderance. I would recommend a 5 lb dumbbell set to go with these as well.
These weights are very sturdy and should last a long time.
Overall these are a very good adjustable dumbell set and it will suite your P90X training well. For women I would recommend the 0-25 set in lieu of the 10-50.
