I want to develop the ability to run a respectable 300 meter shuttle time.
There’s a problem. I don’t have aerobic capacity past that of being able to run a couple 40’s with 4 minutes rest between them.
I’d be lifting weights at least 5 days a week.
All I have is between 6-10pm to workout.
If you can’t give me any advice are there any books you could suggest that would take me from not even being able to crawl to a full speed sprint?
