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.
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. Mustroph ML, Chen S, Desai SC, Cay EB, DeYoung EK, Rhodes JS. Neuroscience Program, The Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL, USA. Neuroscience. 2012 September 6;219:62-71. Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males. Griffin EW, Mullally S, Foley C, Warmington SA, O’Mara SM, Kelly AM. Department of Physiology, School of Medicine, University of Dublin, Trinity College, Dublin, Ireland. Physiology & Behavior. 2011 October 24;104(5):934-41.. Ready to apply for a Nobel Prize? 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.
Flabby arms can ruin your confidence – and your looks. Some men and women are genetically predisposed to carry fat in this area. Luckily, there are ways to slim your arms and improve muscle tone without even leaving home. Just keep in mind that you can't spot reduce fat. You need to eat clean and work your whole body to get results. Certain exercises, especially those targeting the triceps, are particularly beneficial.
It zaps anxiety. Ever notice that you can start a workout feeling stressed and anxious, and end it feeling good? It isn't in your head. Or, actually, it is: According to a new study from Princeton University, exercise appears to change the chemistry of the brain by causing the release of GABA, a neurotransmitter that helps quiet brain activity and minimize anxiety. The study found that people who ran regularly had a low reaction to stressful situations, even if they hadn't run in more than 24 hours.
If you're ready to move on from classic Bulgarian split squats, Swan's amped-up variation gets your upper body in on the action for a true total-body exercise. "This combination move works your legs, butt, chest, back, arms, and core," she says. "And it not only hits all the major muscle groups—it also lets you work on balance." Give it a shot and you'll see why.
Push-ups aren’t everyone’s cup of tea, but when you’re trying to get rid of that excess arm fat, they’re a pretty killer workout. Push-ups not only tone your biceps and triceps, they’re a great way to build muscle on your chest, making you feel stronger and look leaner in the process. If the thought of doing traditional plank push-ups has you feeling nervous, try doing the same motion at a 45-degree angle against a wall; you’ll get a similar workout, but without the intensity of a traditional push-up.
If you struggle with a touch of fatigue, exercise might be just what the doctor ordered. According to a study from the University of Georgia, the blood flow benefits from exercise help carry oxygen and nutrients to muscles, which helps them produce more energy. They found that even low-to-moderate intensity exercise for just 20 minutes a day, three days a week for six weeks can help with that can't-keep-my-eyes-open feeling.
Lifestyle factors have a huge impact on certain conditions – and diabetes is one of them. Exercise can help to reduce your insulin requirements, lower your cholesterol levels and high blood pressure, and in the long term can reduce the development of heart disease and stroke. This is important because diabetics have a higher risk of developing heart and circulatory problems. Exercise can also promote weight loss, improve circulation and reduce stress levels (raising your glucose level).
After ingestion, carbs are converted into glucose and burned for fuel or stored as glycogen in the liver and muscles for later use. According to the European Journal of Applied Physiology, each gram of glycogen stored in the muscles holds at least 3 grams of water. The more carbs you eat, the more water you'll hold, which can make your arms look fuller.
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.
Lie on your back with the knees bent and feet hip-width apart. Place arms at your side and lift up the spine and hips. Only the head, feet, arms, and shoulders should be on the ground. Then lift one leg upwards, keeping the core tight. Slowly bring the leg back down, then lift back up. Try to do 10 reps per leg, then bring the knee in place and spine back on the floor.
When many people decide to "get fit," they assume it involves rigorous activity. But you don't have to spend hours in a gym to be physically active. People can get in shape by performing everyday activities in the home. Every time you and your child throw a softball, swim a lap, climb a flight of stairs, walk to the store, or carry packages, your health and fitness levels are improving.
The first thing to keep in mind while trying to reduce flabby arms is that you need to start watching the amount of calories you consume. Studies say that one needs to burn about 3,500 calories to burn a pound of fat. While the amount seems daunting, there is a simple way to achieve this goal. Try cutting down about 500 calories from your daily diet and over a week, you would be able to burn 3,500 calories. Jot down everything you eat and the calorie content of it, in a notebook, for an easier way to keep track of your consumption.
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.
