I bought these because I was having trouble barbell deadlifting without developing huge callouses on my hands and thought this would also help me grip the bar better. I don’t use them for any other lift, as I’ve never found a reason to. No other lift damages my hands as much as barbell deadlift, although I could see these being pretty useful for pull ups/chin ups if you don’t have padded bars to use.
It ended up protecting my hands very well, and gave me a better grip. Much more convenient than straps and weight lifting gloves although straps help reduce the amount of forearm strength needed (which these pads do not). Overall a great product and would recommend.
Only con I can really think of is the smell. Only used a few times but there is a distinct rubbery smell that stays on your hands for a little while after using this product. My guess is the smell will slowly fade, but I haven’t used it long enough to be sure.
