I sometimes like to do 15 minute runs on my cardio days because its my favorite speed/distance to run. I usually do these in the morning before breakfast, having just water, maybe a piece of fruit beforehand. Before I run I do a light and short resistance training doing lunges and leg curls and then 1 or 2 other isolation workouts I couldnt fit on my lifting day.
When I do my run, I do it at just about 100% effort.
My question is, is there anything really wrong with doing this?
