I feel that whenever I do a set of squats, it tires me out a lot and I have to take like a 2 minute rest in between sets. Is this normal?
For instance:
I squat the bar about 10 times just to warm up a bit
I then start with 245x10
then continue 255x10
and finish 275x8
and sometimes i do the bar about 15x to practice good form
Am I doing something wrong?
