Suboptimal effort is killing your gains

🔴 Instead of worrying about suboptimal exercises, worry about suboptimal effort.
The last reps should be hard, teeth grinding, soul crunching, and face reddening. You will make the worst faces in your life.
You do not have to go to absolute failure all the time but at least get closer to it. Your body will adapt to the high level of effort, get stronger and build more muscle.
