Exercise recommendations for cardiovascular health

EXERCISE: SUMMARY OF SOME NEW SCIENTIFIC ARTICLES To spark conversation, I am summarizing a few recent scientific studies on EXERCISE published in the last year or so 1. Exercise variety may matter: A 2026 BMJ Medicine study looked at long-term cohorts and found that people doing a greater variety of physical activities had lower mortality risk, even after accounting for total physical activity volume. In plain English: walking is good, but walking + strength training + cycling/swimming/sports may be better than doing only one thing (reference:BMJ Med. 2026 Jan 20;5(1):e001513. doi: 10.1136/bmjmed-2025-001513) Physical activity types, variety, and mortality: results from two prospective cohort studies Reminder for Brown Hearts: Yoga alone is great, but NOT enough on it’s own PLEASE make sure you have a portfolio of exercise: Aerobic, Strength training and flexibility 1. Leisure-time and transport activity help; occupational activity may not A 2025 Scientific Reports NHANES analysis found that meeting guidelines through leisure-time physical activity or transport-related activity was associated with lower CVD odds. Meeting ≥150 min/week through leisure activity was linked with about 22% lower odds of CVD, and transport activity with about 40% lower odds. But occupational physical activity did not show the same protective association (Reference: Scientific Reports volume 15, Article number: 35341 (2025) This supports the idea that hard physical labor is not the same as structured exercise with recovery Reminder for Brown Hearts: Working hard at work is good, but does not count as exercise that helps cardiac health 3. HIIT continues to show strong cardiometabolic benefits A 2025 meta-analysis in sedentary populations reported that HIIT can improve cardiorespiratory fitness, metabolic health, vascular health, blood pressure, resting heart rate, arterial stiffness, and endothelial function. It also notes that HIIT is time-efficient, which matters for sedentary people who “don’t have time.” Important caveat: HIIT should be introduced gradually, especially in people with risk factors or symptoms. 4. Yoga-based cardiac rehabilitation from India A 2025 Scientific Reports legacy follow-up from Bengaluru examined yoga-based cardiac rehabilitation after CABG. It followed an original randomized trial and reported that yoga-based cardiac rehab showed better long-term survival/MACE signals than conventional exercise-based rehab, though the authors note limitations including single-center design and male-only participants. (Reference: Scientific Reports volume 15, Article number: 20068 (2025) This is interesting for India because yoga may be culturally acceptable, low-cost, and scalable—but it should be framed as adjunctive cardiac rehab, not a replacement for medicines or standard care 5. Indian older adults: physical activity linked to lower heart disease A study using LASI data from India found that among adults ≥60, adequate physical activity was associated with 28% lower odds of CVD (heart disease) . It estimated that about 9.3% of CVD cases in this older Indian population could be prevented by increasing physical activity from inactive to adequate levels.
