You're protecting yourself against colds, flu, you name it. Exercise elevates your level of immunoglobulins, which are proteins that help bolster your immune system and ward off infection. "Every sweat session you do can help strengthen your immune function for about 24 hours," says Cedric Bryant, PhD, chief science officer for the American Council on Exercise.
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.
As people enter their forties and fifties, muscle mass starts to decline because of aging and, in some cases, decreased activity levels. Muscular atrophy can also occur because of health conditions, such as joint pain. As we age, it’s important to increase or maintain muscle mass through strength training, not only because it helps burn calories, but also because muscle mass is essential for strength and balance.
Begin with a free weight in your right hand. Rest your left hand and bent left leg on the exercise bench. Your left hand should be directly under your left shoulder so it supports your body. Bend your right hand while holding the free weight, making sure your back is straight and your torso is almost parallel to the floor. Form a 90-degree angle between your forearm and your upper arm. Keep your head up and your neck straight.
Before anyone’s crowned Cap’n Crunch, remember form is key. Lie on your back with the knees bent and feet flat on the floor. With hands behind the head, place the chin down slightly and peel the head and shoulders off the mat while engaging the core. Continue curling up until the upper back is off the mat. Hold briefly, then lower the torso back toward the mat slowly.
While building strength will get those arms more defined, cardio is still king when it comes to shedding the fat that’s causing your arms to wiggle. Researchers at Duke University studying 119 overweight, sedentary subjects found that those who stuck to a cardio program lost twice the weight of those who did strength training, despite the fact that the cardio group spent 47 fewer minutes exercising every week than their weight-training peers. So, if you’re ready to get that upper body toned and tight, make sure you’re making time for cardio, too.
HOW TO DO IT: Start with your left leg forward and your right leg back. Place your left foot onto one end of a towel and grab the other end in your right hand. Pull the towel as hard as you can without holding your breath. Hold for 30 to 60 seconds, then switch sides and repeat. If you can’t maintain the hold continuously, break it up into shorter five- to 10-second bursts with brief one- or two-second rests in between.
HOW TO DO IT: Stand with your feet together and hold both arms straight in front of you, palms together. Jump your feet apart, push your hips back, bend your knees and lower into a squat while pulling your arms apart and squeezing your shoulder blades together. Shift your weight over your right leg, and then your left leg, then right and left again before returning back to center and standing back up. Gradually increase your speed and range of motion throughout the set.
