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.
Exercise has been shown to lengthen lifespan by as much as five years. A small new study suggests that moderate-intensity exercise may slow down the aging of cells. As humans get older and their cells divide over and over again, their telomeres—the protective caps on the end of chromosomes—get shorter. To see how exercise affects telomeres, researchers took a muscle biopsy and blood samples from 10 healthy people before and after a 45-minute ride on a stationary bicycle. They found that exercise increased levels of a molecule that protects telomeres, ultimately slowing how quickly they shorten over time. Exercise, then, appears to slow aging at the cellular level.
When she's working out sans equipment, Marraccini's favorite exercises are all things core-related. "A strong core never goes out of style," says Marraccini. This makes sense, considering that having a strong and stable core is essential for both everyday movements as well as exercising. While regular crunches really only target the upper portion of your abdominals, runner's crunches work your entire core as you sit all the way up, including your obliques, lower back, hip flexor muscles, and rectus abdominis (which is what you probably think of when you think "six-pack" muscles).

In addition to the direct beneficial effects of exercise on the heart, regular exercise also improves several important cardiac risk factors. Exercise lowers blood pressure, helps prevent obesity, reduces triglyceride levels, increases HDL cholesterol levels, and improves insulin resistance (and thus helps to prevent or even reverse metabolic syndrome ). An exercise routine has even been shown to be helpful in achieving smoking cessation.

Begin in a plank position on the forearms. Press the hips up toward the ceiling while staying on the forearms (like an upside 'v') and gently press the heels to the floor. Hold briefly, then come back to your plank and push up onto the hands. Hold (back straight) for a few counts and then press back into a downward dog, stretching the heels to the floor and the chest gently through the arms. Come back into your plank, lower down to the elbows and repeat the entire series.

"This is one of my go-tos for home workouts because of how it strengthens the postural muscles," says Bloom. In other words, it's excellent for targeting your posterior chain (or the backside of your body), and that's important for improving posture, preventing back pain, and making sure you have balanced strength—which is a major key to healthy overall movement, both in and out of a gym.
Septh and Chase’s previous comments also apply to lunges. Unlike standard squats, lunges involve a major shift of weight since you’re stepping forwards or backwards. Septh calls them lunge complexes because you’ll make forward, reverse, and lateral moves. Don’t get stuck thinking this move only targets your legs, though. No matter the variation, you’ll be working your glutes, calves, and hamstrings. You’ll also use your core and lower back for balance. Doing lunges also increases the flexibility of your hip flexors.

Then, step your left foot directly behind you (about 2 feet) and bend both knees to lower into a reverse lunge, creating two 90-degree angles with your legs. In this positioning, your shoulders should be directly above your hips and your chest should be upright (not leaning forward or back). Your right shin should be perpendicular to the floor and your right knee should be stacked above your right ankle. Your butt and core should be engaged.

Use small weights to do weighted punches. Pick up a small, 1 or 2 pound weight in each hand and stand with your feet hip-width apart. Bring your hands up in front of your face with your palms facing each other. Punch your right fist forward without locking your arm, then quickly pull it back as you shoot your left fist upward. Alternate the exercise this way for 60 seconds, as fast as you can.[5]

Whether we’re fully conscious of it or not, we’re always looking for how to be happy. And exercise is one of the most obvious steps to take, as it’s not a coincidence that you feel better after a good workout: It’s science. A Penn State University study found that people who exercised, whether it was a mild, moderate or vigorous workout, had more pleasant feelings than those who didn’t. (1)
