The more you do the same workout each week, the faster you recover and the less sore you get.

When you do the same weight workout more than once, your muscles get better at handling it — so next time, you’re less sore and damaged.

You don’t need to feel sore or have high blood markers to get stronger—your muscles can adapt and grow without damage.

Doing varied weight workouts might hurt your muscles a little less than doing the same routine over and over—but you still gain just as much muscle, meaning you don’t need to feel wrecked to get stronger.

Repeated exposure to resistance training induces the repeated bout effect, leading to reduced muscle damage, inflammation, and swelling over time.

If you lift weights until you literally can't do another rep, you'll feel more tired right after than if you stop a couple reps before failure — even if you're someone who regularly lifts weights.
