Fitness on the road

Do 1 to 3 sets of each exercise, 8 to 15 repetitions per set.

Push-ups: Keeping your body straight, balance yourself on your palms and the tops of your thighs, just above your knees. Bend your elbows to lower your body toward the floor until your upper arms are parallel with the floor and then push yourself back up. If those are too challenging, you can also do push-ups off the wall or dresser or the edge of a sturdy chair.

Squats: Stand with your feet hip-width apart with your hands on your hips. Bend your knees as if you are sitting down in an imaginary chair that's directly behind you. Stand back up without over-straightening your knees.

Lunges: Straddle your legs a stride's distance apart. Slowly bend your knees until you are in a kneeling position with your knees not quite touching the floor. Don't look down, and don't allow your knees to shoot out past your toes. Return to standing.

Dips: Sit on the edge of the desk or sturdy chair and place your hands on either side of you next to your buttocks (fingers facing down). Slide yourself off the seat and support yourself just with your hands. Slowly lower yourself by bending your elbows until your upper arms are parallel to the floor, and then press yourself back.

Crunches: Lie on your back with your knees bent, feet flat on the floor and hip-width apart. Place your hands behind your head without lacing your fingers together, and round your elbows slightly inward. Curl your middle body up and forward until your head, neck and shoulder blades clear the floor. Hold a moment before lowering again.
