Lifting weights has a long list of benefits, but one of the biggest risks of either doing it in improper form or going too heavy is that you can wind up with back pain. According to a chiropractor, there’s another factor in strength training workouts that can also put your back at risk: the number of reps that you’re doing throughout your session.
