This is something I’ve always wondered, but could never really find an answer (probably because everyone is different).
I know the general consensus among the majority of people these days regarding medium/low intensity cardio, is that it is simply a means of burning calories (as well as strengthening the heart and lungs).
I do agree that cardio like running or biking is going to build little (if any) muscle, unless you were previously a very sedentary person to start with.
I do “feel” however, that if you take someone who is on the smaller side (say 5’ 10" 150 lbs.) who does not participate in “much” physically (no cardio, weight training etc…), and then you take the same guy at the same weight who runs his ass off for an hour a day, that the guy who runs for an hour a day is going to be considerable leaner then the guy who doesn’t.
For example, my uncle was always on the skinny side (5’ 10" 150 lbs.), but ever since he starting running miles, he looks like he is carved out of stone, but his weight has remained the same. He was always reasonably lean (12% or so), but now he looks well under 10% bf for sure.
Now I’ve also heard of people who lost a lot of muscle doing cardio (usually bigger guys).
What are your guys’s experiences with doing cardio (running in particular), and body fat?
when i started in 2003, 200lbs ish of skinnyfat, i ran and ran and did resistance training (to say lifting weights would be an exaggeration). guess what, i dropped bodyfat and didn’t lose muscle, in fact gained a bit because i was a beginner.
moving on a bit, started weight training harder and upped the calories and kept up the cardio and…
gained very little.
moving on a bit more; upped the calories some more, decreased the cardio a little, gained much better.
decided to cut, increased the cardio and…
lost all the gains.
present day. dropped the cardio.increased calories some more, got stronger, beginning to move some weight now. gained 17 lbs in 12 weeks.
conclusion,well draw your own.
(cardio in this case was running, 30-40 mins ish, not jogging. you don’t need to be a big guy to lose muscle.)[/quote]
Your experience sounds almost exactly like mine…although I was in worse shape than you when I sarted. I had to drop a shit load of fat though (50 lbs.)
After losing the 50 lbs. (compound lifts, medium intensity cardio), I had saved all my muscle. When I tried to bulk up after my fat loss, cardio just slowed the process.
I stopped doing the cardio for a while, had very good gains, then incorporated 400m track sprints, and hill sprints. My weight stayed the same, but my body fat really shot down.
Did you run every day? How intense were your runs?
Thanks for the input:)
