The Claim

In resistance-trained men, high-intensity resistance training (3–5RM at ~90% 1RM with 3-minute rest) and high-volume training (10–12RM at ~70% 1RM with 1-minute rest) result in comparable improvements in squat strength following an 8-week training program, with no statistically significant difference between the two protocols.

In plain English

If you're a guy who's already used to lifting weights, doing heavy sets with long rests works just as well as doing more reps with shorter breaks when it comes to getting stronger in the squat after 8 weeks.

In resistance-trained men, high-intensity resistance training (3–5RM at ~90% 1RM with 3-minute rest) and high-volume training (10–12RM at ~70% 1RM with 1-minute rest) produce similar improvements in squat strength over 8 weeks, with no significant difference between protocols.
