Why it’s a winner: You can walk anywhere, anytime. Use a treadmill or hit the streets.
How to: If you’re just starting to walk for fitness, begin with five to 10 minutes at a time. Add a few minutes to each walk until you get to at least 30 minutes per walk. Then, quicken your pace or add hills.
2. Interval Training
Why it’s a winner: Interval training boosts your fitness levels and burns more calories to help you lose weight. The basic idea is to vary the intensity within your workout, instead of going at a steady pace.
How to: Whether you walk, run, dance, or do another cardio exercise, push up the pace for a minute or two. Then back off for 2 to 4 minutes. How long your interval should last depends on the length of your workout and how much recovery time you need. A trainer can fine-tune the pacing. Repeat the intervals throughout your workout.
Why it’s a winner: Squats work several muscle groups — your quadriceps (“quads”), hamstrings, and gluteals (“glutes”) — at the same time.
How to: Keep your feet shoulder-width apart and your back straight. Bend your knees and lower your rear as if you were sitting down in a chair. Your weight should be evenly distributed on 3 points of your feet — heel, outaside ball, inside ball — that form a triangle. Your knees won’t stay in line with your ankles that way, but there will be less strain on other parts of your body. Add dumbbells once you can do 12 reps with good form.
Why it’s a winner: Like squats, lunges work all the major muscles of your lower body. They can also improve your balance.
How to: Take a big step forward, keeping your back straight. Bend your front knee to about 90 degrees. Keep weight on your back toes and drop the back knee toward the floor. Don’t let the back knee touch the floor.
Why it’s a winner: Push-ups strengthen your chest, shoulders, triceps, and core muscles.
How to: Facing down, place your hands slightly wider than shoulder-width apart. Place your toes on the floor. If that’s too hard, start with your knees on the floor. Your body should make a straight line from shoulders to knees or feet. Keep your rear-end muscles and abs engaged. Bend your elbows to lower down until you almost touch the floor. Lift back up by pushing through your elbows, Keep your torso in a straight line throughout the move.
Push-Ups: Too Hard? Too Easy?
If you’re new to push-ups you can start doing them by leaning into a kitchen counter. As you get stronger, go lower, using a desk or chair. Then you can move onto the floor, starting with your knees bent. For a challenge, put your feet on a stair, bench, or couch while keeping good form.
6. Crunches — Method A
Start by lying on your back with your feet flat on the floor and your head resting in the palm of one hand and the other hand reaching toward your knees. Press your lower back down. Contract your abdominal muscles (abs) and in one smooth move, raise your head, then your neck, shoulders, and upper back off the floor. Tuck in your chin slightly. Lower back down and repeat.
Crunches — Method B
You can also do crunches with your feet off the floor and knees bent. This technique may keep you from arching your back. It also uses your hip flexors (muscles on your upper thighs below your hip bones).
Keep your neck in line with your spine. Tuck in your chin so it doesn’t stick out. Breathe normally. To keep chest and shoulders open, keep your elbows out of your line of vision.
