In the next training session I can then run 200m 5 times and do the same, eventually on the fifth session I should be able to run 500m and see by looking back on my times that it is quicker and more efficient than the first time I did it! I can also then go back and run the 100m after I have completed the 500m and see weather or not the time has improved from the last 100m I did. If the time has improved it has shown that as a result of the training program my stamina has improved! I could also do various lengths one after the other (when I have regained resting pulse rate) and record times and pulse rates after each run the repeat the process and compare the times and pulse rates and if they have improved I have gained more stamina therefore succeeding in my task!
Sit-ups Doing sit-ups the same way as the running will also improve stamina. I can gradually increase the number I do each time and do as many as possible then over a certain amount of time I should be able to do more in a quicker time than when I first started doing it! There for once again my stamina has improved!
All of the above sorts improve stamina if done for more than 20 minutes a day, so I cold take up one of then e.g. tennis and then play it every night for around half an hour. I should find that I am able to play for longer without tiring in the end and therefore I have improved my stamina!
Skipping Skipping is a good method of improving stamina as it involves a lot of tiresome work. A good way to use skipping would be to skip on the spot for 2 minutes counting how many jumps I manage to fit in I can the repeat the skipping a few times and hopefully if my stamina had improved I will be able to fit more jumps in 2 minutes and so again improved stamina! I can take jumps and heart rates to show this point!
