Those buff lab rats might be smarter than we think. Various studies on mice and men have shown that cardiovascular exercise can create new brain cells (aka neurogenesis) and improve overall brain performance Aerobic exercise is the critical variable in an enriched environment that increases hippocampal neurogenesis and water maze learning in male C57BL/6J mice.

Studies suggest that a tough workout increases levels of a brain-derived protein (known as BDNF) in the body, believed to help with decision making, higher thinking, and learning. Smarty (spandex) pants, indeed.

Quick Q&A: Which is better at relieving anxiety — a warm bubble bath or a 20-minute jog? You might be surprised at the answer. The warm and fuzzy chemicals that are released during and after exercise can help people with anxiety disorders calm down. Hopping on the track or treadmill for some moderate-to-high intensity aerobic exercise (intervals, anyone?) can reduce anxiety sensitivity Effects of aerobic exercise on anxiety sensitivity.

Another way lunges differ from traditional squats is that they train each leg individually. This is known as unilateral training. Rather than solely improving your strength, unilateral exercises increase your balance and coordination. This brings your core and back strength into play. Focusing on one leg at a time with lunges can even help with symmetry and muscular imbalances.
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.
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.
Exercise has long been correlated with a longer life, but it’s only recently started to become clear why this might be. Studies, like a new one in the journal Preventive Medicine which found that exercise is linked to longer caps at the ends of chromosomes, have helped flesh this out a bit more. These caps, called telomeres, naturally shorten as we age, with each cell division. People who live a long time have telomeres that are in better shape than those who don’t—but there’s a lot we can do to affect the rate at which they shorten over the years. The team behind the new study looked at data from CDC's National Health and Nutrition Examination Survey, and found that for people who exercised regularly, their telomeres were 140 base pairs longer on average than sedentary people's. Which correlates to being years “younger” than their sedentary peers.
A 2002 study examined three groups of people. Group one, the control group, was told to track how often each person exercised throughout the week. The second group, the motivation group, was given the same instructions, but also read a motivational speech. Group three, the intention group, added on to the previous groups by asking people to create a plan that set a specific day, time and place to exercise.
Step forward with the left foot and lower into a lunge, keeping the front knee behind the toe. Push into the heel to step back and immediately step out to the left and into a squat. Press back to start and take the left leg back into a reverse lunge, again keeping the front knee behind the toe. Bring the left leg back to start and repeat for all reps before switching sides.
For the greatest overall health benefits, experts recommend that you do 20 to 30 minutes of aerobic activity three or more times a week and some type of muscle strengthening activity and stretching at least twice a week. However, if you are unable to do this level of activity, you can gain substantial health benefits by accumulating 30 minutes or more of moderate-intensity physical activity a day, at least five times a week.

"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.
Some call it “flab”, others call it “sag”, or even “jiggle.” Whatever it is that you call the excess fat on your arms, know that you’re not alone. A lot of us have found ourselves in the dilemma, wondering how to lose arm fat and why it’s even there in the first place. Is it something I ate? Is it something I did or didn’t do? What shirt can I wear to hide to cover those parts?
Carbs and fats are essential for our body to function properly. Eat foods that are rich in good fats and carbs. Foods like brown rice, oats, wheat bread, sweet potatoes, multigrain cereal, dark chocolate, avocado, whole egg, chia seeds, nuts, fatty fish, rice bran oil, etc. are highly nutritious and keep a lot of health problems at bay. Avoid fried foods, potato wafers, cream cheese, donuts, cakes, flour products, polished rice, cakes, pastries, milk chocolate, etc. Even if you choose to eat them, make sure to workout to burn the extra kilos. Also, eat good fats and carbs in measured amounts.
Exercise acts as a temporary diversion to daily stresses and it improves self-esteem. Increased core temperature during exercise may lead to reduced muscle tension and favourable alterations in brain neurotransmitters. Mood improvements may also occur due to the increased secretion of endogenous (internal) opiates, e.g. endorphins. Psychological changes may occur because of changes in norepinephrine, dopamine and serotonin, all hormones which can affect mood and anxiety levels.
FIT TIP: If you exercised on an empty or almost-empty stomach, you're probably feeling light-headed or even nauseated or headachy. Your immediate food fix: A high-carb nosh, like a banana or half a bagel, will refuel you and kick-start your recovery. And don't forget to drink plenty of water with your snack. Intense or long workouts can leave you dehydrated.

The skin also serves as a release point for heat. (See “Why Does My Face Turn Red When I Exercise?” for more on that.) When you exercise, your muscles generate a lot of heat, which you have to give up to the environment so your body temperature doesn’t get too high, Hackney says. The heat in the muscle transfers to the blood, which shuttles it to the skin; it can then escape into the atmosphere.

To perform reverse curls you will need a barbell with weight, enough to provide a challenging workout but not so much that you can’t complete a third set. Hold the bar at your waist in an overhand grip with your feet about shoulder-width apart; this is your starting position. Then you simply perform your basic curl exercise, flexing your muscles to lift the bar to shoulder level and return to starting position.

Mediterranean diet: Traditional cuisine of countries bordering the Mediterranean Sea, shown to reduce the risk for heart disease, diabetes, some cancers and dementia. On the menu: Plenty of fruits, vegetables and beans, along with olive oil, nuts, whole grains, seafood; moderate amounts of low-fat yogurt, low-fat cheese and poultry; small amounts of red meat and sweets; and wine, in moderation, with meals.


Studies have consistently shown that physical activity can help treat depression, and on the flipside, that low activity levels are a big risk factor for it. The antidepressant effect of exercise seems to be moderated in part through serotonin, the brain chemical that’s targeted with some antidepressants, and in part through bone-derived neurotrophic factor (BDNF). And this goes back to the generation of new cells mentioned earlier—exercise, though various mechanisms, seems to make the brain more plastic and more capable of growing new cells.
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.
A new study from her lab shows that a 20-minute moderate workout has measurable effects on the immune system: Participants were asked to walk or jog on a treadmill, depending on their fitness level. They measured levels of TNF, an inflammatory marker, before and after the exercise, and found that there was a 5% reduction in the number of immune cells that produced the marker.

This one is a big one, since inflammation may be an underlying cause of a wide range of diseases and disorders in both body and brain. Exercise is known to reduce a number of inflammatory markers, like c-reactive protein (CRP) and internleukin-6 (IL-6), which are linked to a number of diseases. “The thing about exercise is that it has a multitude of effects on many different organs and systems,” says Suzi Hong, who studies exercise and immune system activation at the UC San Diego School of Medicine, “so often it is difficult to pinpoint which organ systems are influenced and which ones are not with which specific effects for what conditions… The anti-inflammatory effects of exercise are likely one of the underpinnings of its effects against cardiovascular disease, diabetes, certain cancers, neurodegenerative conditions and more.”

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.

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.
