The Claim
In young men undergoing resistance training three times per week for nine weeks, consistently performing the same exercises for each muscle group results in a greater increase in isometric knee extension strength (12%) compared to varying the exercises for the same muscle group (7%), indicating that exercise consistency may enhance specific isometric strength gains.
What the research says
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.
If young guys stick to the same exercises every time they work out for about two months, they get stronger in a specific leg test than if they keep switching up their routine.
See the scientific wording
In young men performing resistance training 3 times per week for 9 weeks, maintaining the same exercises for each muscle group leads to a greater increase in isometric knee extension strength (+12%) compared to varying exercises for the same muscle group (+7%), suggesting that exercise consistency may enhance specific isometric strength gains.
What the research says
1 studyStudy: Does Varying Resistance Exercises for the Same Muscle Group Promote Greater Strength Gains?
The study found that young men who did the same leg exercises every time got stronger in a specific knee test compared to those who changed exercises, which supports the idea that sticking to the same moves can help build certain types of strength.
