Resistance training under hypoxic conditions (RTH) provides a trivial but statistically significant benefit for strength development (1RM) compared to normoxic training (RTN) when specific methodological variables are optimized.

If you have access to hypoxic training, you can gain a small advantage in strength over normal air training, but only if you structure your workout correctly. Focus on multi-joint exercises, do at least 9 sets per muscle group per week, and stop short of muscle failure (non-failure). Do not train to failure in hypoxia, as it may increase fatigue without adding benefit.
