Lifting until failure only benefits strength development in experienced lifters
Training to failure doesn’t seem to benefit beginners when it comes to strength and hypertrophy. This is probably due to nervous system fatigue which compromises later sets if failure occurs too early.
For experienced lifters there seems to be some benefit on the last set, but as long as you train with enough volume (sets and reps), you will grow!
