The Claim

In trained young men, resistance training performed once or twice per week with equal volume results in no significant improvements in elbow flexor or extensor peak torque, indicating that strength gains are minimal or absent in already trained individuals regardless of training frequency.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

For men who are already trained, doing resistance training once or twice a week with the same total workload does not lead to measurable increases in elbow strength, suggesting that further strength gains may not occur even with different training frequencies.

See the scientific wording

In trained young men, resistance training performed once or twice per week with equal volume produces no significant improvements in elbow flexor or extensor peak torque, suggesting that strength gains may be minimal or absent in already trained individuals regardless of frequency.

Why this might work

When someone is already strong, their muscles and nerves don't respond much to the same amount of lifting they've done before. Their body has already adjusted to that level of effort, so doing the same work once or twice a week doesn't push them hard enough to get stronger.

  1. Study: Effects of equal-volume resistance training with different training frequencies in muscle size and strength in trained men

    This study found that even if trained guys lift weights once or twice a week with the same total effort, their arm strength doesn't get noticeably stronger. So, if you're already strong, just doing a little more training won't make you much stronger.
