I am 6 feet 2 inches tall. I have been eating and exercising in the “evolutionary” or “primal fitness” way for about 18 months, and I was in good physical condition prior to that. I have been lifting weights for years. I am fit and active with a low percentage body fat. My stomach is flat. You can tell that I have abdominal muscles. But here is my hang up: I can’t seem to pack on any extra muscle. I weigh in at 150 pounds. I am the ultimate hardgainer, as they say in the iron game. I’m not looking to become huge. I have a lanky, Jimmy Stewart kind of frame, and no amount of training will turn me into Arnold. But what the heck does a guy have to do to gain a lousy 5-10 pounds of muscle? — Ed
Ever heard of it?
If you are a regular to MDA and you subscribe to a Primal Health lifestyle I’m guessing it is likely. If not, now you have.
Crossfit is a type of physical training that blends power lifting, gymnastics and sprinting. Why do we like it? Because it fairly closely aligns with our Primal fitness philosophy in which variety, weight-bearing activity and anaerobic exercise is key. Here is a great description of CrossFit:
CrossFit maintains that proficiency is required in each of 10 fitness domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy. CrossFit uses free weights, kettlebells, gymnastics rings, pull-up bars and many calisthenics exercises. CrossFit may call on athletes to skip, run, row, climb ropes, jump up on boxes, flip giant tires, and carry odd objects. They can also squat and explode up to bounce medicine balls against walls.
CrossFit workouts typically call for athletes to work hard and fast, often with no rest. Many CrossFit gyms use scoring and ranking systems, transforming workouts into sport. CrossFit publishes its own journal and certifies its own trainers. Many CrossFit athletes and trainers see themselves as part of a contrarian insurgent movement that questions conventional fitness wisdom.
A research study out this week indicates type II muscle mass associated with strength training not only helps reduce body fat but alters overall metabolism.
Researchers from the Boston University School of Medicine (BUSM) have demonstrated that in mice, the use of barbells may be as important to losing weight and improving health as the use of running shoes. The discovery builds upon the fact that skeletal muscle consists of two types of fibers. Endurance training such as running increases the amount of type I muscle fibers, while resistance training such as weightlifting increases type II muscle fibers. Using a mouse genetic model, BUSM researchers demonstrated that an increase in type II muscle mass can reduce body fat which in turn reduces overall body mass and improves metabolic parameters such as insulin resistance. These studies indicate that weight bearing exercise, in addition to endurance training, may benefit overweight people.
