The Study
The application of training to failure in periodized multiple-set resistance exercise programs.
This isn't a science experiment — it's more like a coach sharing their thoughts. It doesn't prove anything, but it gives ideas about when lifting to failure might help or hurt. We can't say if it really works because no test was done.
Analysis score
Maximum 0 for a editorial/opinion.
Where the score came from
Some strong people think you need to lift until your muscles are totally tired to grow stronger, but this paper says you don’t have to. Doing it once in a while might help really strong lifters get past stuck points.

You can still build muscle even if you don't push your sets to within five reps of total failure, which goes against the idea that only the last few tough reps really matter for growth.
If you're an experienced lifter trying to get stronger, building more muscle—like by sometimes pushing your sets to the max—can help boost your strength over time.
If you're an experienced lifter stuck in a plateau, doing some sets until you can't lift anymore might help you break through — but only if you do it once in a while. Doing it too much could lead to burnout or overtraining.
If you're lifting weights and want to see real gains, pushing yourself to failure only works if you're using heavy weights and doing enough sets and reps. If the weight or volume is too low, it probably won't help much.
