Most of us do everything in our power to keep our faces from developing wrinkles, but we do little else for the rest of our body.
Exercise is the single most important thing you need to do to keep your body looking and feeling young. The problem with skin on our bodies is not that wrinkles start showing, but that areas start sagging very soon. In fact, skin on the top underside portion of our arms start sagging as early as our late-twenties. We thus need to keep muscles strong and in shape by working out regularly.
If you wanted to take up an exercise but were unsure as to which you should take up, consider swimming. Swimming tones your arms, legs and stomach, and essentially gives your entire body a workout without causing excessive strain. Chances of injury while swimming are low, while other exercises such as jogging, can cause knee strain and other injuries.
If you cannot swim or don't have access to a pool, you could consider two of the most convenient exercises - walking and jogging.
If you have tried various exercises only to give them a short while later, consider taking up a sport. You may find that you stick with it once you get the hang of it and enjoy playing it. This does take time though, and you will need access to sports facilities. You will also need to know likeminded people who you can go and play with - or continue being regular with the sport until you get to know others around. Once you are familiar with everyone who plays the sport, you will enjoy the game much more.
If you cannot swim, don't have access to a club or sports facilities, and are looking for options to walking or jogging since you're not very fond of solitary activities, consider joining a class. If it takes a class for you to be regular, then, by all means, go for it. You could consider yoga or aerobic classes. Alternatively, you could also consider joining dance classes. Dancing is a strenuous activity, and in addition to exercising, you will learn something new and exciting, and will become more graceful in the bargain!
Having trouble with motivation? Tell yourself that exercise is not a choice. Just like you have to wake up every morning, and you have to eat your breakfast, so also you have to work out daily, or three times a week. Sure you could work out less than that - any exercise is better than no exercise - but the more regular you are, the healthier you will be at a later age. My 70-year-old grandmother who is so regular with yoga, can still sit up with her back straight and her legs crossed, and even bend over backwards if she has to, while her friend recently broke a bone in her arm trying to pull a sweater over her head.
Similarly, a 55-year-old colleague, who to this day plays squash daily, always enthusiastically leads the way when we go on treks, while my 53-year-old boss would rather stay back at the campsite waiting for us, as he nurses a bad back.
Set a time to go exercising, and stick by this time. If you decide to workout when you have a little free time, you will find that within a month you will have less and less free time, and soon your exercise routine will have flopped. Fix your workout time, and plan other activities around it, instead of the other way around.
