About a month and a half ago I started lifting. Started out doing bicep curls with 20lb being the most I could handle for only a small amount of reps. I'm now up to 40lb weights doing 10x4 or however many sets afterwards that I feel like. I generally move onto heavier weights when the old weights feel too light, which seems to happen magically. For example, I didn't have the chance to work out at all for 3 days during Thanksgiving. Before Thanksgiving I was doing 35lb weights with moderate difficulty. When I got back the 35lb weights magically felt a LOT lighter.
So when do you know when to move onto heavier weights? Is 20lb increase in 1.5 months pretty slow?
