I was always interested in finding ways to increase my stamina so that I can do more physical feats and work harder without getting tired. In my quest, I have found a few exercises which can be really very helpful in this regard to build and improve stamina.
1. Skipping: Start small. Skip for some time daily - as long as you feel comfortable. Each week try to increase the duration a little. This can have a good effect on increasing your stamina.
2. Running on the Spot: Run on the spot for a set period of time, like 2 minutes to start with. Later as days pass by you can increase it to maybe 5 minutes etc.
3. Swimming: Everybody must be aware of the good effects of swimming. It is a very good exercise. If you make a habit to swim at least 30 minutes everyday it can do wonders for your stamina.
4. Cycling: This is another very good exercise for increasing stamina vastly. All the above mentioned exercises not only improve our stamina, they come with a wide range of other health benefits too.
5. When working out, keep in mind two things: overload and progression. Overload is necessary to improve stamina, but don't overdo it. If you are getting irritable or depressed, they can be the first signs of fatigue. Progression means to keep on improving.
I hope that I include many of the above exercises in my daily schedule for a long time to come.What about you? In addition to improving stamina, we also need to have high energy throughout the day to do our work.
Always remember this, when you do those activities that you enjoy, then its easier to stick to them in the long run so that you can keep enjoying increase in stamina. So try to find out a few activities from the above ones which you really love and then stick to them on daily basis.
That's all there is to increase your stamina, physical endurance and be fit!
