Performing resistance training sets to concentric failure is necessary to optimize strength and muscle mass gains when using low loads (30-50% 1RM), whereas it is not necessary and potentially counterproductive when using high loads (>70% 1RM).
If you are training at home with light weights or bands, push your sets until you can no longer complete a repetition with good form (concentric failure) to ensure you get strength and muscle benefits. If you have heavier weights, you do not need to go to failure on every set; stopping a few reps short may allow you to do more total work and recover better.
In conclusion, when using low loads (30-60% 1RM), performing sets to concentric failure seems to be necessary to improve strength and increase muscle mass. When high loads are used, however, high-threshold motor units are already recruited, and training to failure does not appear to bring an additional benefit.
