It seems unlikely that more than two weekly resistance training sessions would provide any further benefits for older adults.
Practitioners should consider limiting resistance training sessions to two per week for older adults to optimize benefits.

Considering that muscle hypertrophy was not affected, while maximum strength was only slightly improved with additional training days, it seems unlikely that more than two weekly resistance training sessions would provide any further benefits for older adults.
Why this rating
Based on meta-regression analysis of multiple studies.
