I was a physical Therapist. A simple exercise to kee the legs strong is: 1)Take a chair and raise the level of sitting with some firm Pillows. Put the chair in front of the sink. Holding onto the sink, Do deep squats.(Not below the knee level), Sets of 5 or 10. While at the sink, Come onto your toes on one side 5-10 time. Repeat on the opposite side and and do both for a series. Bend your knee, while at the sink and flex each knee 2 or 3 series of 5 or ten. At the sink, with your knee bent, extend you hip 2-3 series of 5 or ten. At the Sink, move your leg sideways in abduction 2-3 series....Sitting in a chair, extent your leg 2 sets of 20. Sitting, lift your knee up with hip extension 3 sets of 10. Sitting, raise your arms over head( turn your thumbs out when you are shoulder high. No weight 3 sets of 10. Standing, put your hands behind your head and go to your hands behind your back at the waist. 3 sets of 5-10. Lying down on the bed on your back lift one leg as high a possible with the other leg stationary and bent with the bed flat. Repeat. Reach forward as far as possible for the abdomine. Reach up and over for the obliques. You can repeat this with your legs bent. With legs straight, arch your back slightly, hold, do the pelvic floor kegel exercise (anus contraction), hold and then do a mild pelvic tilt.hold for 50-100 count This is the correct way to do a core exercise. Just walk back and forth, side ways and backwards in the house. Too long or to much trouble? I do them every day and I am 90 yrs old. So it will take 30-45 minutes of your time. Try limiting food when not out of the house. No junk food. Cook your own. Limit your sugar. Cut down on alcohol. What? What? Who is this guy anyway.. A friend.
