The doctor will perform an electrocardiogram, check for any breathing problems, high cholesterol levels, and high blood pressure before giving the go-ahead for a vigorous exercise program. Anyone, regardless of age, should check with a doctor if a cardiac condition, weight problem, or other medical complication already exists. Running asks a lot of your body, so make sure your body's ready to run. The Importance of Stretching Before beginning an exercise regimen, proper stretching is essential. If muscles are properly warmed up, the strain on muscles, tendons, and joints is reduced.
Many experienced runners prefer to jog easily for a half-mile or so before stopping to stretch.
After a run, repeating the same stretching process allows the body to cool down and reduces muscle stiffening the next day. Face a wall from three feet away, with feet flat on the floor, and knees locked. Lean into the wall, keeping feet on the floor and hold for 10 seconds as the calf muscle stretches, then relax. Do not bounce. Repeat five times.
