Things You'll Need:
- A safe place to run
- Good running sneakers
- Hand weights
-
Step 1
Run faster. Running faster works the obliques, which builds more muscle in the abdominals and gives you a nice flat stomach.
-
Step 2
Carrying hand weights while you run will help to build muscle in your arms and upper body.
-
Step 3
Sprinting will build muscle mass in your legs. During your run, take time to increase your intensity, then reduce back to a steady run.
-
Step 4
Know that uphill running will build muscle in the quadricep muscles, hamstrings and the buttocks.
