Progressive resistance exercise (PRE) significantly improves the ability of individuals with various impairments (including COPD, hypertension, chronic spinal pain, and osteoarthritis) to generate muscle force, with moderate to large effect sizes.
If you have a condition that weakens your muscles (like COPD, back pain, or arthritis), progressive resistance exercise is a safe and effective way to rebuild strength. Start with weights you can lift 8-12 times, rest between sets, and gradually increase the weight as you get stronger. This improves your ability to perform daily tasks. Always consult a physical therapist to ensure the program is tailored to your specific condition.
Across conditions, PRE was shown to improve the ability to generate force, with moderate to large effect sizes that may carry over into an improved ability to perform daily activities.
Why this rating
Based on 18 systematic reviews, many of which were high quality (e.g., 16/18 score), though some heterogeneity exists in protocols.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
