Piccadilly saidOr asked differently, does jogging impede muscle building progress in the legs from regular weight training?
Since I've started jogging again, my leg training has become more "painful", even though I do the same exercises, weight, number of series and reps as before. Something's up.
Jogging is catabolic...that is it burns muscle. And it will burn muscle all over your body, not just the legs.
xrichx saidSprinters have large legs because that type of running stimulates muscle hypertrophy differently than marathon running. If you're only running 5K - 10K, then I don't think you have much to worry about. Just increase your calorie intake if you think you're losing muscle mass.
Exactly. Sprinting is fine, and even beneficial to gaining muscle.
Look at the difference between Olympic sprinters (beefy builds) and marathon runners (skin and bone).
So, if you like running (don't understand why so many people claim to love it...for me, it's torture)...but if you love it, then just do some short sprints.
Ditch the jogging. Leave it to the hipsters.
