Endorphins are hormones in the brain associated with a happy, positive feeling. A low level of endorphins is associated with depression. During exercise, plasma levels of this substance increase. This may help to ease symptoms of depression. A recent National Health and Nutrition survey found that physically active people were half as likely to be depressed.
FIT TIP: To trim your tummy, do fewer crunches and more planks: Begin on all fours, hands under shoulders, knees under hips, then lower forearms to floor and extend legs straight behind you, balancing on toes. Keeping abs engaged and back flat, hold for 30 seconds; do 10 reps three or four times a week. Limit crunches to no more than three sets of 15 at a time. Anything beyond that isn't doing you much good, experts say.
Strength training, whether you’re lifting weights, doing bodyweight exercises or incorporating yoga moves, helps improve muscle strength and muscle mass, particularly important as we age. (8) It also keeps bones strong, thus serving as a great natural treatment for osteoporosis. Plus, increased muscle helps your body burn calories more efficiently long after your workout is over.
One of the easiest ways to tone those arms fast is by incorporating some bicep curls into your routine. Simply raising and lowering a weight in a 180-degree range of motion, starting with your arm extended along your side, and bringing it up toward your shoulder, can yield serious definition in a hurry. Fortunately, this exercise doesn’t require a fancy gym membership or even special equipment; while it’s not hard to find a set of dumbbells for under $10, you can also use household products, like gallon jugs of water or soup cans to get the same result.
Science is also showing that even short bursts of exercise can have a significant impact on your brain function in the short term. A study published in January 2018 in the journal Neuropsychologia found that when participants cycled for 10 minutes (either moderately or vigorously) on a stationary bike, their measured reaction times to a cognitively demanding task were significantly more accurate and faster than when they did the task after not doing any physical activity, meaning their attention was sharper.
Ah, the push-up. While lunges are a unilateral exercise, push-ups are a compound exercise. Compound exercises use several muscle groups at once. This classic move engages your core, biceps, triceps, deltoids, and lower body—and that’s just to keep you stabilized. Using this many muscle groups at once causes your heart to work harder to get oxygen-rich blood to your muscles. So, in short, push-ups can also be a form of cardiovascular exercise that increases heart health.
Starting your day with a workout could be the key to getting rid of those jiggly upper arms at record speed. Researchers at Northumbria University found that, among a group of physically active male study subjects, those who hit the gym before eating breakfast burned nearly 20 percent more fat than those who fueled up before exercising. So, if you’re eager to shed that fat fast, a fasting workout can help you achieve those goals right on schedule. When you’re back home post-workout, nourish your muscles with the best breakfast foods for weight loss and you’ll keep your metabolism going strong all day.
