| Headache & migraine | Do this | Moderate | RCT / meta-analysis | Regular moderate aerobic exercise (30-50 min, 3-5x/wk) cuts migraine frequency/severity 30-40%, sometimes exceeding oral preventives. | Lifestyle-migraine meta 2024; American Migraine Foundation (opens in a new tab) |
| Headache & migraine | Do this | Moderate | RCT / meta-analysis | Regular moderate aerobic exercise (30-50 min, 3-5x/wk) cuts migraine frequency/severity 30-40%, sometimes exceeding oral preventives. | "The relationship between lifestyle behaviors and tension-type headache and migraine: a systematic review and meta-analysis", Medicine 2025 (opens in a new tab) |
| High blood pressure | Do this | Strong | RCT / meta-analysis | Dynamic resistance lowers BP ~4.5 mmHg, and isometric training (wall-squats, handgrip) ranked the single most effective form, lowering systolic BP ~8 mmHg. | Exercise training & resting BP (NMA) (opens in a new tab) |
| High cholesterol / dyslipidemia | Do this | Strong | RCT / meta-analysis | Resistance training lowers LDL and triglycerides and raises HDL (LDL down 6-16 mg/dL in trials; a 148-RCT meta confirms exercise improves the lipid profile). | Exercise training & blood lipids meta (opens in a new tab) |
| Insomnia / poor sleep | Do this | Strong | RCT / meta-analysis | Muscle-strengthening (resistance) exercise was the single most effective modality for sleep quality (SUCRA 94.6%). | Exercise-sleep NMA (older insomnia) (opens in a new tab) |
| Muscle & joint pain / weakness | Do this | Strong | RCT / meta-analysis | Resistance training is the most effective exercise for building muscle strength and mass (grip strength SMD 0.81, knee-extension SMD 1.26) and reversing sarcopenia; it also stabilises painful joints. | Resistance training & sarcopenia meta (opens in a new tab) |
| Obesity / weight gain | Do this | Strong | RCT / meta-analysis | Resistance training lowers body-fat percentage and fat mass and best preserves/builds lean mass (raising resting metabolic rate); combined with aerobic is optimal. | Resistance training & body-composition meta (opens in a new tab) |
| Osteoporosis / low bone density | Do this | Strong | RCT / meta-analysis | Resistance and weight-bearing exercise build and preserve bone (Wolff’s law); consistently linked to higher BMD and lower fracture risk. | Exercise & bone density (IOF) (opens in a new tab) |
| Osteoporosis / low bone density | Do this | Strong | RCT / meta-analysis | Resistance and weight-bearing exercise build and preserve bone (Wolff’s law); consistently linked to higher BMD and lower fracture risk. | Effects of dynamic resistance exercise on bone mineral density in postmenopausal women: a systematic review and meta-analysis, Osteoporos Int 2020 (opens in a new tab) |
| Peripheral neuropathy | Do this | Moderate | RCT / trial | Resistance training (with aerobic) improved nerve function and glycemic control in diabetic neuropathy. | Exercise & nerve conduction (opens in a new tab) |
