Four sessions of resistance training per week produced greater gains in muscular strength for the upper body measures (1RM bench press and arm curl) compared to two sessions per week.
Increasing the frequency of resistance training sessions can enhance upper body strength gains.

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).
