I bought some 2 1/2 and 5 lb rubber stack weights to add on top of the weight stack, which is in 10 lb increments from 10-150 lbs.
It's much easier for them to transition 2 1/2 lbs at a time, 40 to 42.5 to 45 to 47.5 to 50 lbs, while doing tricep put downs. Versus jumping from 40 to 50 lbs. in one 10 lb increment. This is where I'm really seeing the biggest jumps. Just adding a little weight at a time.
This is good advice. I also use 20-ounce "bat doughnuts", as 2.5-pounds can become too big of a jump.
