4. Grip strength And Heart Health
Weak grip predicts a higher risk of heart attack or stroke and lower chances of survival, according to a new Lancet study of nearly 140,000 adults in 17 countries.
Grip strength was a better and cheaper predictor of death than blood pressure and other common medical test.
This test determined overall muscle strength and fitness, which suggests that whole-body strength training and aerobic exercise could reduce overall risk of death. (source)
