descriptive

No matter if trained men do 5 or 20 sets per muscle group each week, they all get stronger and their muscles get thicker after 6 months of training.

Scientific Claim

Resistance training volumes of 5 to 20 sets per muscle group per week are all associated with significant increases in muscle strength and thickness in trained men over 24 weeks, regardless of volume level.

Original Statement

“All groups showed significant increases in all 10RM tests and MT measures after 12 and 24 weeks when compared to pre (p <0.05).”

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design cannot support claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim uses 'associated with' and reflects the abstract’s explicit statement of significant increases across all groups. No causal language is used, and the conservative verb strength is appropriate given unknown methodology.

Evidence of a Ceiling Effect for Training Volume in Muscle Hypertrophy and Strength in Trained Men - Less is More?

Randomized Controlled Trial

Human

2020 Feb 1

Doing more sets didn’t make people stronger — in fact, those who did 15 or 20 sets got weaker gains than those who did only 5 or 10 sets, so more isn’t always better.

Similar Assertions

When trained men do 15 or 20 sets per muscle group each week, they don’t get as strong as those doing only 5 or 10 sets — more work doesn’t mean more strength.

94%

For guys who already lift weights, doing 5 to 10 sets per muscle group each week builds strength and muscle just as well as doing 15 to 20 sets — more sets don’t help much.

94%

No matter how many sets trained men do — 5 or 20 — their muscles grow about the same size after 6 months.

84%

Even though the guys doing the most workouts looked like they might have grown a little more, the difference wasn’t big enough to say for sure that more sets = more muscle.

84%

Doing more sets of leg exercises makes you lift more total weight in one session, but doesn’t make you stronger right after or cause your muscles to swell longer.
