Im trying to build muscle. Im also trying to build my cardio. Should I lift or run first in my work out.?

Answer 1

But for most of the guys, they want some serious mass, and let me tell you that the last few reps (Say the last 3-2 reps) where you struggle and sweat is where you stimulate your muscles to grow. But when you run before working out, an intense cardio workout totally or almost depletes your glycogen stores.

When weightlifting, you dont use as much of your glycogen stores, but you still need quite a bit (This might come as a surprise to some people but its true).

So if you have no glycogen stores which is your muscles source of energy and your pushing yourself to max, the energy wont be there to push those last few grueling reps meaning a way less effective workout.

Another reason why this is such a big NO is because during a hard cardio session, protein synthesis drops low and protein breakdown goes up. During a weight lifting session, protein synthesis either goes up a little or stays the same while protein breakdown goes up.

After your cardio session while protein synthesis drops (Meaning your bodys ability to build muscle), and you hit the weights, the result will be that your bodies ability to build muscle will be impaired because of your cardio training depending on how intense your cardio was.

You have to balance the running and lifting equally.

Answer 2

Better to run after your workout. If you run before your workout, you will deplete crucial energy that would of been better used during your weight work out. The best thing is to do cardio on days that your not doing weight training. But if you have to do cardio on weight training days; always do it after your workout.

Good luck

I always heard to run after a good workout was the way to go or u can go to burgerking and order triple woppers everyday and forget about working out and just become obese and someday u will be so fat u cant get off the couch so u poop and pee on yourself because ur 2 lazy to make it 2 the bathroom.Build muscle first and then cut it is the way 2 go obese sucks and diapers suck.
