During lockdown, I am doing workouts at home with two dumbells. I can't add any more weight, so I am doing sets in the 15-25 rep range.
How many sets should I aim for per week for large (leg, chest, back) and small (arms) muscles per week?
The goal is muscle growth.
Also, how much time to rest between sets? Due to the low weight, I am trying to add more tension by going to failure often and resting little between sets. Good idea or not?
