Just started with strength training? Training to failure isn't necessary, making enough sets is...
Study
The first group made 3 sets, and trained to failure [RF].
The second group made 4 sets of 7 reps, and did not train to failure [NRFV]. Because of the extra set, the training volume in this group was equal to that of the first group.
The third group also did not train to failure, but made no more than 3 sets [NRF].
Results
The muscle size of the women in the to-failure group [RF] increased more than that of the women in the not-to-failure group [RNF]. But that also applied to the muscle size of the women who trained not-to-failure, but did an extra set [RNFV].
The increase of the number of reps the women were able to make didn't differ between the groups.
Conclusion
"On the other hand, only those groups who performed a greater total volume of repetitions increased their muscle thickness. This result suggests that the subjects elbow flexor muscle hypertrophy may be optimized using a greater volume of total work, whereas muscle fatigue (i.e., repetitions until failure) does not add any additional stimulus."
"From a practical standpoint, repetitions until failure are not necessary to optimize the enhanced muscle strength and endurance induced by strength training. It seems that there is a stimulus threshold in which training with more repetitions does not provide further strength gains."
"On the other hand, within the volumes investigated, it seems that a greater volume of total work may be a necessary to achieve muscle hypertrophy in previously untrained women."
"Training until concentric failure should be further investigated, including studying their effects in longer training periods and other periodization models."
