Increase the incline on your treadmill, or conquer a more challenging walking path. You’ll not only firm up your butt and legs, but you’ll also maximize the calories you burn by up to 60 percent.
Your Fat-Burning Walking Plan
Don’t lean. Maintain an upright posture; keep your shoulders over your hips; your hips over your ankles.
Start easy. Do a 5-minute slow walk and then a 10-minute brisk pace before adding your first hill.
