To begin with, do not confuse exercise with sports. There is more to getting healthier than chasing a ball around on a football field. Walking is a great place to start. Post-operatively, just walking to the next-door neighbors or to the end of the garden is fine. When you begin to regain your strength, walk more - both for pleasure and as an alternative means of transportation. Moreover, when you do, walk briskly - so you get slightly out of breath. Gardening is great too. Digging, weeding, hoeing and mowing can constitute a superb day's workout. Of course, you will have a showpiece garden to show for it. Wait for about three months after surgery before beginning gardening. You will be surprised at how quickly you will feel the benefits. After a few aches in the early days, you will begin to feel suppler and be able to do more without getting out of breath.all doctors agree on the benefits of exercise, but it is a good idea to talk to your doctor before starting an exercise program, especially if you are very out of practice or if you have other health considerations, like asthma or a heart condition. Your doctor will advise you to take it easy to begin with and to enjoy yourself. You cannot obtain better advice than that.
