Lifting very heavy weights often causes people to hold their breath while exerting force, which can dramatically increase blood pressure. This sudden pressure may be risky for individuals with hypertension or cardiovascular disease.
Using lighter weights with controlled movements and higher repetitions is generally a safer option while still helping maintain muscle strength and bone density.
### **4. Long-Distance Running Without Preparation**
Running long distances can provide excellent cardiovascular benefits, but only when the body is properly conditioned. For someone over 60 who is new to exercise or returning after years of inactivity, long-distance running may put excessive strain on the heart, joints, and muscles.
Building endurance gradually with walking, swimming, or shorter runs is a much safer approach.
### **5. Extreme Endurance Challenges**
Activities such as marathon races, ultra-distance cycling events, or intense obstacle courses demand prolonged physical effort that may be too taxing for an aging heart. These events can lead to dehydration, overheating, abnormal heart rhythms, and excessive fatigue if the body is not adequately prepared.
