i'm really in a workout slump right now. i've hit a plateau and its really affecting my motivation. I just starting mixing it up in hope of breaking through it. I switched from 3 sets of 10 reps to 2 sets of 20 reps mostly to increase endurance for climbing. my number one goal for the next month is to get my nutrition back on track tho. summer is usually just crazy with always being on the go and stuff and its made it tough to eat right.
If you hit a plateau just increase your weights, dont increase your reps and sets. Thats virtually the same thing. Even if you are trying to increase your endurance its true that more reps will do that, but you need to either change your workout or increase your weights. Muscles have an incredible memory so you wont be doing anything to them by doing the same thing over and over again.
