When should you go up in weight?

By this I mean, when should you start adding more weight to your squats, dumbbell curls, etc.

I always try to get at least 8-10 reps in my sets. If I can get 12, then for sure the weight is too light and I could’ve added a few extra pounds.

There’s really no specific time frame. Some say to aim for 5 pounds added per week but most likely there will be times for weeks maybe even months when you struggle to add weight, so don’t let that discourage you.

I always say it’s better to do 4 reps with heavy weight than 15 reps with light weight.
