Try...
This girl can rise ~53 lb (24 kg) ball 200+ times

Why? As an endurance competition?


Kettlebell sport in Russia means rising fixed weight (16, 24 or 32 kg)kettles (1 or 2) as much time as possible. Yes, it is endurance sport.

I'm really only compelled to get my spinnaker under control. One arming it for a long downwind leg can be very tiring. On at least one occassion I was absolutely out of breath BEFORE the end of the leg.

IMHO, some elastic is better than kettlebell, may be because I hate dropping kettle on my foot.
