Building up my stamina

This week I would like to show you my plan for the new year, which is to improve my stamina. My stamina level is very low right now, some focused training on that would help me a lot to achieve my future goal, to start swimming again.
To increase it I have to use this training plan and challenge my conditions a little bit more each week. 

1st week:

10 minutes warm up, with different stretches focusing on your legs. 

Start with jogging slow for 2 minutes and increase the tempo until you have a comfortable         running speed. When you achieved that speed level run for 10 minutes, take a break for 2 minutes and run for another 5 minutes.

Do 5 minutes on a step machine, take a break for 2 minutes and do another 5 minutes.

2nd week:

1. 10 minutes warm up.
2. Jogging with increasing your speed level
3. Run for 15 minutes with the current speed level that you are on for 2
4. 7 minutes on the step machine

3rd week:

1. 10 minutes warm up
2. Jogging with increasing your speed level
3. Run for 10 minutes, take a break for 1.30 minutes, run 10 more minutes
4. 10 minutes on the step machine

4th week:

1. 10 minutes warm up
2. Jogging with increasing your speed level
3. Run for 15 minutes, take a break for 1 minute, run 10 more minutes
4. 10 minutes on the step machine

  

This training plan is very effective if you want to increase your stamina, because it challenges you to the extreme every week. Furthermore it is very easy to understand and to follow. I will also do some secondary exercises, since you need your whole body for swimming.  I will also try to do regular do some Yoga, because it concentrates on your works strengths, connection and balance.
