Sit on the floor with your legs and feet joined together, knees bent and feet placed flat on the floor. Place your hands on the floor about a foot behind your hips, palms kept shoulder-width apart and fingers pointing towards your back. Now, raise your hips off the floor by straightening your arms. Bend your right elbow to lower your hips as close to the floor as possible, without touching it. Straighten your right arms and bend your left elbow to again lower your hips as close to the floor as possible. Repeat on alternate sides.
A certain level of muscle strength is needed to function every day and do things such as walking and climbing stairs. Strengthening exercises increase this muscle strength by putting more strain on a muscle than it is normally accustomed to receiving. This increased load stimulates the growth of proteins inside each muscle cell that allow the muscle as a whole to contract.
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.
