WARM UP COLD MUSCLES
One of the easiest ways to get hurt during a workout — especially on brisk mornings when you first wake up and muscles are tight and cold — is to skip a pre-routine warm-up. Yet, it takes only five simple minutes to sidestep most exercise-induced sprains, strains, and pulls if you start with these easy moves.
Two minutes: Walk in place, gradually lifting knees higher and higher and pumping arms more vigorously. Shake out your arms and legs as you go.
Two minutes: Progress to alternating knee-lifts, touching opposite elbow to knee, which hits the larger muscles of the lower body, including butt and thighs.
One minute: Finally, start slow-jogging in place, keeping heels low to the ground and arms swinging close to your sides. You are ready and set - to go!
