Effective ways to increase fitness level?

Just wondering if anyone can help me out with some tips on ways to effectively increase my fitness level? Especially cardiovascular fitness.

At the moment I have been eating healthy and going for daily jogs, plus doing sit-ups/push-ups, etc and some cycling each day.

I am 19, female, 186cm tall (6'1") and currently weigh 84kgs (184.8 lbs)



Also, about how long would it take to go from a non-existent fitness level, to one where I could, say steadily jog for about 3 kilometres?



Thanks!Effective ways to increase fitness level?instead of jogging at the same pace, make your body work harder,

Fartlek Training;

if you run on a track this is what you can do to increase your fitness level:

for 3/4 of the track, jog and on the home straight, sprint flat out. Repeat this several times - i do it about 6 or 7 times but it depends on your fitness.

This is the best way to increase your fitness level.

If you dont live near a track, just jog for 3 minutes and sprint about 100m

Your doing a lot already and that's great. Health is so important to how we feel. The only thing i can think of is swimming. With summer coming, swimming is a great all around exercise. Plus it is low impact. Whereas say jogging can be rough on your knees etc over time. But you put me to shame. Keep up the good work!
