The Claim
Upper and lower body resistance training programs induce divergent patterns of muscle hypertrophy, indicating that differentiated training volume prescriptions are necessary to optimize regional muscular development.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When you train your upper and lower body, your muscles don't all grow at the same rate. To get the best overall results, you probably need to adjust how much you train each specific area instead of using the same routine for everything.
See the scientific wording
Upper versus lower body resistance training programs present potential methodological and practical considerations, as the majority of combined training studies report divergent patterns of muscle hypertrophy rather than uniform growth across all targeted muscle groups. This suggests that regional adaptations may require differentiated volume prescriptions to optimize overall muscular development.
What the research says
1 studyThe review shows that when people train both their upper and lower body, their muscles often grow at different rates instead of evenly. This means training programs might need to adjust the amount of exercise for each body part to get the best results.
