The Sport Series is the third generation of PowerBlocks new in June of 2008. The Sport Series consists of 4 models of PowerBlocks with unique differences in both form & function. As far as form goes, the dramatic changes would be the Gray color of the steel weight plates vs. the black weight plates of other PowerBlock models and the rounded shaped top of the weight plates offering a stylish look. As far as function differences, the Sport Series has tapered handles, double tethered selector pins (not on the Sport 2.4) , the wrist supports are of a more open design offering a larger handle cavity and the dial locks are recessed into the handle.
The Sport 5.0 equals/replaces 10 pairs of dumbbells or 550 lbs of free weights. The weight range for the 5.0 is 5-50 lbs per hand in 5 lb increments. Weight increments achieved are; 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 lbs per hand. The 5.0 can be further expanded to 65 lbs per hand with the optional Sport 5.0 Set 20 lb cores.
