Four sessions of resistance training per week produced greater gains in muscular strength for upper body measures (1RM bench press and arm curl) compared to two sessions per week.
For optimal strength gains, practitioners should consider recommending four sessions of resistance training per week.

Group × time interactions were also noted in 1RM bench press (effects size [ES] = 1.07 vs. 0.89) and arm curl (ES = 1.15 vs. 0.89), with greater gains for RT4 than RT2 (p=0.03).
Why this rating
Based on the randomized controlled trial design.
