Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Whether you rest 1 minute or 2.5 minutes between sets, your strength gains in squat and bench press end up being about the same after 10 weeks of training.

See the scientific wording

Resistance training with either 1-minute or 2.5-minute rest intervals produces similar increases in squat and bench press strength after 10 weeks in healthy, recently untrained males.

  1. Study: The Effect of Resistive Exercise Rest Interval on Hormonal Response, Strength, and Hypertrophy With Training

    The study found that whether guys rested for 1 minute or 2.5 minutes between weightlifting sets, they both got just as strong in squats and bench presses after 10 weeks — so the rest time didn’t matter for strength gains.
