I'm feeling that it's time to make a change in my exercise program. For the last bunch of years I've been doing lots of barbell weight training, primarily back squats, dead lifts, and bench presses. I've got a good amount of muscle mass but I'm getting burned out on the hard work and reaching the point of diminishing returns and I'd like to explore bodyweight exercises, MovNat kinds of movements, mobility work, ways of becoming more flexible with more flowing movements (e.g. Prasara Yoga), getting back into running and maybe exploring gymnastic movements (yes, they'll be very hard too but at least it'll be a change).
My question: Can I cut down my weight training to, say, 75% of my current level and maintain muscle mass? Can I go down to 75% and drop from 3x/week to 2x/week and still maintain the muscle mass I've gained?
I'm 48 and I guess I'm going through a mid-life-exercise-crisis. While the weight lifting has made me strong, and given me a decent amount of muscle, the longer I do it the harder it is to stay lean. I was once upon a time 10% body fat, doing a zone diet and lots of cardio. A few months ago I was 15.5% body fat and now, suddenly, I'm at 17.5% and I think the heavy weight training is making it very difficult to eat less so the fat packs on with the muscle.
I'd rather be lean than muscled and I've been influenced by the writings of Mark Sisson and others that less is more and that more natural movements can be good for fitness. Plus, I wouldn't mind spending much less time in the gym.
