Haphazardly loading a barbell and doing one set until you fall in exhaustion shouldn’t be the plan for the majority of lifters.
I’ll bet you’ve heard of training to failure. It’s popular in the always do more attitude that’s seeped into the strength and fitness communities. This style of training usually makes the mind wander to images of Arnold and other classic bodybuilders. They grunt loudly in dusty gyms and fall on the floor after doing so many reps. Nearly everyone associates this with good blue-collar work.
