I have just completed another stretch of in home therapy. This therapist was unique in his approach. He really pushed the value of isometric exercises. These are the exercises you perform like pushing against a wall or a railing. They are 'static' meaning that you don't move your muscles or limbs through their full range of motion. You just focus on a muscle group and then make it work. For example, to do an isometric on your bicep muscle, sit at the table with correct posture. Place your hand under the table and try to lift it for a count of ten. You'll feel that tonight! Please, that's just an example. Be well informed before you try any exercises on your own!!!!
It has been two months and I am really beginning to notice results that carry over to my daily routines. The great thing is you can do these types of exercises anywhere.
He also stressed that you should work hard at whatever task you are trying to strengthen your muscles for. If you want to walk better, walk. If you are trying to stand up, try that several times during the day. Practice, practice, practice.
So, we don't need gym memberships, high priced personal trainers or piles of equipment. Keep it simple, be consistent and be persistent. Stay strong and safe.
