Do you need to train to muscle failure for results?
Roberto, Founder, REZA Health & Performance · 9 September 2026
Complete muscular failure is the point at which another repetition is no longer possible. The question is whether every set must reach that point to build strength or muscle mass. The reviewed literature gives a nuanced answer.
A systematic review with meta-analysis (Grgic et al., 2022) compared resistance training to muscular failure with training that stopped earlier. The key finding in the REZA Evidence Library is modest but useful: complete failure is not necessary to build strength or muscle mass.
In practice, complete failure does not need to be the fixed endpoint of every set. The review does not determine what proximity to failure is appropriate for one person. This article does not prescribe individual intensity.
The source therefore does not support a general rule that every set must reach complete failure. How a programme handles proximity to failure requires more context than this single review provides. This article is not individual training advice.
