1.Getting Older
It’s normal to lose some muscle mass and get weaker with age. Doctors call this sarcopenia. You probably won’t notice it much before your 60s or 70s. Sarcopenia also can also come with other health conditions that make you inactive. If your doctor suspects sarcopenia, they may test for it by seeing how fast you can walk.
2.Check Your Medicines
Some medications can weaken your muscles. These include corticosteroids like prednisone and cholesterol-lowering statins. If you feel weak and don’t know why, ask your doctor or pharmacist if it might be a side effect of any medicine you’re taking.
