Strength training (heavy resistance, explosive resistance, or plyometric) performed 2-3 times per week improves running economy, time trial performance, and maximal sprint speed in middle- and long-distance runners.
Add 2-3 strength sessions per week to your running program. Use heavy weights, explosive movements, or plyometrics. This will improve your running economy and race times without making you heavier or slower. Ensure your running volume and intensity remain consistent with your previous training.
Strength training (ST) appears to provide benefits to running economy, time trial performance and maximal sprint speed in middle- and long-distance runners of all abilities
Why this rating
Systematic review of 24 studies, but methodological rigor (PEDro scores) was moderate (4-6) with issues in blinding and randomization.

- 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
