How fast are jogging? If you want larger muscles in your lower body, I'd recommend more sprinting and less jogging. Or cycling with traffic. Trying to keep up with traffic will build up your legs. Take a look at sprinters legs and cyclists legs.That is interesting. I would like to add what you have said to my research. Do you have any sources or links? Sadly, I have noticed that attempting to build muscle in my lower body while jogging 30 minutes per day has not been as effective as weight training without the cardiovascular exercise — my muscles were neither as large nor as firm. Perhaps there is something else in the mix? Anything would help.
I would also have to agree that anyone NOT going for the strongman look or performance can do cardio! I should have been more clear.
