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.
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.
HOW TO DO IT: Place your left foot on a stable low box or step (even a sturdy phone book will work). Hold your right arm forward. Quickly alternate which foot is on the box and which is on the ground from side to side. Stay on the balls of your feet throughout the movement. Perform the move at a slower, more controlled tempo at first, focusing on nice, clean exchanges of your hands and feet, and gradually increase your speed over time.
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.
Exercise and physical activity are a great way to feel better, boost your health and have fun. For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. Examples include running, walking or swimming. Fit in strength training for all the major muscle groups at least twice a week by lifting free weights, using weight machines or doing body-weight exercises.
When it comes to these pushups, make sure your left and right hands are shoulder-width apart to keep proper form. Keep your left elbow and right elbow in as well so you can activate not only your triceps but also your chest. This exercise is great because it helps you protect your rotator cuff, which is upon your shoulders. Shoot for 15 to 20 reps in this 30-second set. Don't go for high speed, go for perfect form.
