As well as being 20% bf I'm also pretty damn unfit, so decided to start sprinting today Post-Workout. I found I could only run about 20 seconds (albeit fast) before needing to rest for half a minute. I repeated this 4 times with slightly decreasing run durations and slightly increasing rest durations. My cv system ached a little afterwards
Am I right in thinking I simply need to repeat the above daily and improve continually until I can sprint 4 minutes, rest 2, and repeat 3 times?
