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.
A Targeting just your shoulders is hard. An overall decrease in body weight will help your shoulders look less broad. Exercise at least three times a week to lose weight and it could also aid in increasing your metabolism, which in turn aids weight loss. There are, however, some exercises you can do. Front raises will help you. - Stand with a dumb bell in each hand with your arms by your side. - Bend your elbows slightly, extend your arms and raise it to chest level - Hold for a few seconds, then lower your arms again.
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.
Bend your knees to lower down into a split squat. Your left knee should ideally form a 90-degree angle so that your thigh is parallel to the ground, and your right knee is hovering above the floor. (Quick position check: your left foot should be stepped out far enough that you can do this without letting your left knee go past your left toes—if you can't, hop your left foot out a bit farther away from the bench.)

“Being active as we age can play a role in cognitive function, and reduce the risk of disease such as dementia and Alzheimer's,” says Amanda Paluch, a postdoctoral researcher at the Northwestern University Feinberg School of Medicine. “Research has explored several mechanisms, finding that exercise can increase synaptic plasticity and strength of nerve impulses in the brain, and have a positive effect on the hippocampus.”

From fortifying your immune system against future cancers to reducing the risk of breast cancer, regular exercise helps protect your body. (12) Although researchers aren’t entirely sure how exercise boosts immunity, theories range from bacteria being flushed out of the body to a reduction in stress-released hormones that might increase the risk of illness.

6. Never do the same arm workout for more than 2 weeks. The female body is a highly adaptable organism. If you do the same workout over and over again, your results will come to a screeching halt. Always have a new workout ready to go every 2 weeks. If you are a beginner, you have a little more wiggle room here. If you are advanced, you have to change your workout even more frequently! Note: doing a different workout every time you walk into the gym will give you the fastest results.
If you want to lose weight and keep it off, you know that exercise should be an essential part of your routine. But the benefits of physical activity go far beyond just physical fitness. Increasingly, more and more research is showing that working out regularly can boost other aspects of your health as well, including cognitive function and emotional well-being.
