Reduce your risk of heart diseases. Exercise strengthens your heart and improves your circulation. The increased blood flow raises the oxygen levels in your body. This helps lower your risk of heart diseases such as high cholesterol, coronary artery disease, and heart attack. Regular exercise can also lower your blood pressure and triglyceride levels.

HOW TO DO IT: Start in a high plank. Push your hips back without arching your lower back until your knees flex to about 90 degrees. Pause for a beat, then explosively extend through your knees, ankles and hips while also pulling with your upper back as you lower into the bottom of a push-up. Keep your elbows tucked into your sides to protect your shoulders. Skip the push-up and just maintain a hold if you need it to be easier.


Inflammation (in-fluh-mey-shun): The redness and warmth around a cut or scrape is short-term inflammation, produced by the immune system to aid healing. But another type called chronic inflammation, triggered by compounds from abdominal fat, gum disease and other factors, lingers in the body. Research suggests this type increases the risk for heart disease, diabetes, dementia and some forms of cancer.
You'll also build muscle to fill out your arms and firm them up. “Generally, when people are complaining about underarm jiggle, they’re usually referring to the area that is governed by the tricep,” says Williams. “If the jiggle or looseness in that part of your arm is due to a lack of muscle, then strengthening and building muscle in your tricep will also create some change in the aesthetic of that area.” She recommends performing triceps push-ups, extensions, and dips to hone in on that area and add some muscular definition to your arms.

Exercise and physical activity are a great way to feel better, boost your health and have fun. For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. Examples include running, walking or swimming. Fit in strength training for all the major muscle groups at least twice a week by lifting free weights, using weight machines or doing body-weight exercises.
So short of moving to a blue zone, exercising for just 10 minutes a day, or 75 minutes a week, can earn you an extra 1.8 years. The findings held true even for those individuals who were overweight or obese; adding exercise helped them live longer, while being obese and inactive decreased life span by up to 7.2 years. The benefits of adding more exercise increased and then plateaued at about 300 minutes of weekly exercise (or an hour five days a week) adding an extra 4.2 years of life.
3. It strengthens the lungs. Working hard increases lung capacity, and their efficiency in moving air in and out of the body. As a result, more oxygen is drawn into the body and more carbon dioxide and other waste gases are expelled. Regular exercise helps prevent the decline in oxygen intake that occurs naturally with age or as a result of inactivity.

Get in plank position with your hands shoulder-width apart (A). Lower your chest toward the floor while keeping your upper arms parallel to your sides and your elbows pointing straight back (B). Push back up to start. That's one rep. Do three sets of 12 to 15 reps, resting for 30 seconds between sets. To make it easier, lower your knees to the ground. There's no shame in girl pushups!
And you don’t need to sweat buckets to see the benefits of exercise, either. According to the physical activity guidelines from the Centers for Disease Control and Prevention (CDC), 150 minutes of moderate-intensity exercise with two days of strength training per week yields the same health benefits as 75 minutes of high-intensity exercise with two days of strength training each week — as does a combination of moderate- and high-intensity exercise, plus two strength training workouts.
HOW TO DO IT: Step to your left and lower your body into a lateral lunge, placing both hands on the floor. Without moving your feet, lift your hands and hips and shift your weight over your right foot, so you end up in a right-side lunge. Alternate back and forth for 30 to 60 seconds. To really kick up the burn, turn this movement into a monkey shuffle by simultaneously loading your hands, lifting your hips and shuffling your feet side-to-side between right and left lunge positions.
And exercise stimulates the endocrine system and can improve reproductive function, explains Berger. The endocrine system is made up of glands that secrete hormones in the body; this system plays a key role in regulating metabolism, mood, tissue function, and sexual function. Bottom line: There are a lot of ways your sex life can get a boost from working out.
Kick your leg up as close to your elbow as you can and then lower it back down and place your foot back on the ground. Once your foot is back down, repeat the push up then kick the other leg out to the side toward your elbow. Keep your leg as straight as you can as you kick it out. Place your foot back and repeat the push up before repeating on the first side.
"You'll definitely feel a minute of boat with the belly drawn in and the chest lifted," says West. It's tough to hold this for the full 60 seconds, but there's no better way to end a workout than with a challenge, right? (That being said, if you are struggling to maintain proper form for the full minute, take a break after 30 seconds, reset, and try holding for another 30.)
Start the clock, and do as many squats as you can — while maintaining perfect form — for 30 seconds. Then rest for 10 seconds, and do as many single-leg deadlifts as you can (again, with perfect form) for 30 seconds. Stick to one leg with the deadlifts for the full 30 seconds. Then rest for 10 seconds again. Finish up with 30 seconds of glute bridges. Rest for a minute or two, and then start all over again.
Really work on burning that fat by going as hard as you possibly can. None of these workouts are going to be as effective as they can be if you're not going at your maximum intensity. Don't worry about the person near you. Don't compare yourself to other people. Just go as hard as you possibly can and have fun doing the thing, ladies and gentlemen. Keep on killing it.
And perhaps one of the best new findings about exercise — especially if you, like many people, struggle to find the time to fit it into a busy day — is that all those benefits of physical activity can be had even if you only squeeze in a few minutes of exercise a day. While doctors used to think that we needed to engage in 30 to 60 minutes of exercise a day, new research is finding that we can see benefits with shorter bursts of physical activity. “As little as 15 minutes a day of high-intensity activity that leaves you breathless, like swimming, can kick start your metabolic rate and reduce body fat and increase muscle mass,” says Dr. Berger.
