Adherence
Splitting a lower-body resistance training session into two shorter intra-day sessions increases total training volume (repetitions) compared to performing the same exercises in one long continuous session.
If you can fit two shorter gym visits into your day with a few hours of rest in between, you might be able to squeeze out a few more reps than if you did one long, exhausting session. However, the gain is small (3%), so prioritize the schedule that you can actually stick to.
GoodSupportsHIGH confidence
The short sessions had 3% higher training volume than the long session (p = 0.002, ES = 0.42).
Why this rating
Randomized crossover design with resistance-trained participants, though sample size is small (n=23).
