Was at The Hills PCYC and got to look in on Erin leading Sweat Depot. Very high energy. You need BIG boxing gloves to protect your hands. Your own pair (they’re like undies – personal!)
Pairs take turns punching a bag hard and very fast using every muscle. You can just see all the muscles rippling under the skin with sweat dripping off. Each turn last just long enough and then there is a rest.
Looks fun.
