The Claim
In a group of 30 obese women aged 17–25, 10 weeks of supervised resistance training using gym machines targeting major muscle groups was associated with statistically significant increases in one-repetition maximum strength across all exercises and a reduction in body mass index.
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.
After 10 weeks of supervised resistance training using gym machines, obese women aged 17–25 showed increased muscle strength and lower body mass index.
See the scientific wording
In a group of 30 obese women aged 17–25, 10 weeks of supervised resistance training using gym machines targeting major muscle groups was associated with statistically significant increases in one-repetition maximum strength across all exercises and a reduction in body mass index, though the absence of a control group prevents attribution of these changes to the intervention alone.
Lifting weights stretches muscle fibers, which triggers the body to build more muscle protein and make muscles bigger. Bigger muscles can produce more force, making it easier to lift heavier weights. The extra muscle also burns more calories even at rest, and the body keeps burning extra calories after each workout. This causes fat stores to shrink, lowering overall body weight relative to height.
What the research says
1 studyAfter 10 weeks of lifting weights on machines, these young women got stronger and lost a little weight, just like the claim says — but we can't be 100% sure the weights caused it because there was no group that didn't train for comparison.
