As anyone who works in a traditional office environment knows, finding time for fitness can be a challenge. However, even if you can’t get to the gym, you can still keep your body strong — having a set of go-to exercises can make staying in shape easier. A quick 15-minute workout that includes a few high-quality, multi-muscle group moves can be just what you need to maintain muscle mass and give your day an extra lift.
In fact, that's what makes these exercises so ideal. With minimum equipment you get maximum results. Also, when you do develop a gym habit and have access to all your favorite machines, you can still do these exercises once or twice a week to maintain strength in your most important muscle groups: quadriceps, glutes, calves, biceps, shoulders, and abs.
Add in 30 minutes of moderate-intensity aerobic exercise on most days of the week — which you can break down into two 15-minute or three 10-minute sessions — and you’ll meet the recommended guidelines from the Centers for Disease Control and Prevention (CDC).
Several of the moves require dumbbell weights (though you can substitute inexpensive resistance bands in a pinch). Use heavy enough weights that the final few repetitions of a set feel challenging. When you're ready to use heavier weights, increase slowly to reduce risk of muscle injury. Do these moves at least three times a week. For upper body exercises, increase the weights in 1- to 2-lb increments; for the lower body, increase in 3- to 5-lb increments.
Strengthens the pectoralis major and minor (chest), triceps (back of arms), and deltoids (shoulders)
Get down on the floor on all fours. Place your hands on the ground directly under your shoulders. Point your thumbs in toward one another, elbows flared out to the sides, and walk your feet out behind you. Keeping your head in line with your spine and your abdominals contracted, inhale and bend your elbows so your body lowers toward the ground, your chest about two inches from the floor. Exhale and push back up to the starting position without hyperextending your elbows. Do 15 repetitions. If you can't complete the repetitions from the traditional push-up position, finish the set on your knees.
Make it harder: Put your feet on an aerobic step or the lowest stair of a staircase, and do your push-ups from a declined position. Be sure to keep your spine, neck, and head in a straight line.
Strengthens the latissimus dorsi (lats) and biceps
Hold a dumbbell in each hand with your palms facing inward (if you've never done this exercise before, start with 2- or 3-lb weights). Stand with your feet shoulder-width apart, knees bent, and bend forward from the hips. Squeeze your shoulder blades together, and allow your arms to hang straight down from your shoulders. Pull your navel in toward your spine, and, keeping your shoulder blades squeezed and your chest open, exhale and pull your elbows up and back until the weights are next to your ribs. Inhale and return to the starting position. Complete 12 to 15 repetitions. Work up to three sets.
Make it harder: Rotate the weight. As you lift the dumbbells, rotate your arms so that your palms face backward, a variation that puts extra emphasis on your biceps.
Strengthens the deltoids
Hold a dumbbell in each hand (if you've never done this exercise before, start with 2- or 3-lb weights. Stand with your feet shoulder-width apart and knees slightly bent. Pull your navel in toward your spine, contract your glutes (your butt), and drop your tailbone so your hips shift slightly forward. Lift your chest. Squeeze your shoulder blades together and raise your arms out the sides, keeping your elbows loose. Stop when the weights are shoulder height. Complete 12 to 15 repetitions. Work up to three sets.
Make it harder: After each set of side-arm raises, add a set of rear raises to target the backs of your shoulders and arms. Stand in the same position as above, holding the weights with palms facing in. Exhale and push your arms up behind you as high as you can. Pause and slowly lower the weights back down. Be sure to keep your body upright for the duration of the move.
Strengthens the gluteus maximus, gluteus minimus (rear-end), quadriceps (front of thighs), and hamstrings (back of thighs)
Stand with your feet shoulder-width apart, toes pointing straight ahead. Pull your navel in toward your spine, relax your shoulders, and make sure your ears are in line with your shoulders. Inhale and bend your knees, shifting your weight slightly so your hips are behind your heels. Stop when your knees are over your toes. Allowing your knees to drift past your toes can lead to injury. Exhale and push yourself back the starting position. Be sure to keep your shoulder blades pulled down and back. At first, do this exercise without weight, but as you get stronger, hold a dumbbell in each hand while you do the exercise. Complete 12 to 15 repetitions. Work up to three sets.
Make it harder: Do plié squats (to work the inner and outer thighs). Stand with your feet out a little wider than in the regular squat, and angle your toes outward. This is called a “plié position.” Lower your body in the same way as you would for the traditional squat above. You may find that you can go lower this way since you're more stable, but don't allow your knees to shoot out past your toes. Push back up to the starting position and repeat.
Strengthens the calves, quadriceps, gluteus maximus, gluteus minimus, hamstrings, adductors (inner thighs), abductors (outer thighs)
Stand in a staggered stance so one leg is about one stride in front of the other and your feet are spread slightly wider than shoulder-width. Hold a dumbbell in each hand (if you've never done this exercise before, start with 3- or 5-lb weights). Pull your shoulder blades back, and contract your abdominal muscles. Keeping the heel of your back foot on the floor, inhale and bend both knees, lowering your hips toward the floor until your front thigh is parallel with the ground. Exhale and push up to the starting position. Complete 12 to 15 repetitions, switch legs, and repeat. Work up to three sets.
Make it harder: Do backward lunges. Step backward with your right leg, taking one full stride. Bend both knees until your left thigh is parallel to the floor and your right thigh is perpendicular to it. Push yourself up to the starting position. Now step back with your left foot and repeat.
Strengthens the rectus abdominis (abs)
Lie face down on the floor. Adjust your arms so they're shoulder-width apart with your elbows tucked to your sides and forearms touching the floor. Squeeze your shoulder blades together, inhale, contract your abs, and push your body up until it's parallel with the floor. You should be supporting your weight with your elbows, forearms, and toes. Your head and neck should be in line with your spine. Breathe smoothly and deeply while you try to hold this position for 60 seconds. If you can't hold it in the correct position for a full minute, finish it out on your knees instead of your toes.
Make it harder: Add alternating leg lifts. While you're in the holding pattern, lift your right leg a few inches off the floor, lower it, and then lift your right. Repeat for 60 seconds.
1. Suck It In
Tightening your abs for the duration of any exercise (imagine you’re pulling your navel back toward your spine) supports your spine and keeps you from arching or rounding your back, which can lead to injury.
2. Just Breathe
Exhale deeply through the most difficult part of the move, and inhale deeply through your nose during the easier part of the move.
Focus on keeping your shoulders down and relaxed — not hunched up around your ears. This helps you maintain proper posture.
4. Lift and Lower on an Equal Count
It can be tempting to allow the weight to drop back to the starting position after you’ve lifted — but don’t! Lift and lower on a four-count to get maximum results for your effort.
5. Watch Your Toes
When doing lunges and squats, make sure that you never let your knees drift past your toes — it puts excess stress on your knees.
Stretching helps keep muscles supple. Make sure you spend at least five minutes before and after each workout stretching your major muscles.
