Tips

Lack of equipment is the reason of not doing exercise but this is not an excuse. If you don't have a reservoir to run around there is an option that you can climb stairs. If you don't visit any gym you can do resistances work with elastic tubing, dumbbells or a bottle of water in each of your hand. Even if you can't manage a workout, there are plenty of exercises you can fit in on the go.

If you don't have time and you have to rush your office you can do one thing that before leaving for the office, perform an imaginary jump-rope sequence and you can do this even in your bedroom. Turn on your radio and jump up and down while twirling your wrists as if holding on to a real jump rope. If you do fifteen minutes of this technique, it will help you work up a sweat.

While sitting at your desk try to jostle your feet up and down rhythmically and keep them moving. This is helpful to improve blood circulation and tighten calf muscles. Every hour you can stand up and stretch gently without tearing your muscles, reaching arms high and bending from side to side a moment or two. Even slight movements can add up over the course of a few days.
