More Modified CrossFit Routines
Since the CrossFit post I’ve received several requests for more “CrossHIT” routines - CrossFit routines modified to be more consistent with high intensity training principles. The difference between these and more bodybuilding-oriented HIT routines is a greater emphasis on metabolic conditioning and incorporation of more bodyweight and gymnastic exercises, which I believe are of considerable value. While there may be no positive transfer of skill from bodyweight or gymnastic movements to different movements, regular performance may improve general kinesthetic sense and proprioception as well as awareness of and confidence in one’s physical abilities.
CrossFit’s Greg Glassman has described the method as “constantly varied functional movement executed at high intensity” . Although an exercise is commonly considered to be “functional” if it mimics a movement of daily living, work or sport, since only the strength gained from an exercise will transfer to other movements and not any specific skill, any exercise that effectively strengthens the body and contributes to improvements in other general aspects of fitness could be considered functional. By replacing the Olympic lifts and certain other movements with exercises involving the same muscle groups you do not sacrifice any functional benefit. It is unnecessary to move fast during exercise to develop speed and power in other activities and there is no transfer of skill from an exercise to a different movement. For example, the skill of performing power cleans will not positively transfer to the different although superficially similar movement of a football lineman exploding off the line any more than the skill acquired performing football blocking drills will positively transfer to swimming. › Continue reading
Warming Up
Most of the physical benefits of a warm up - increased blood flow to the muscles, enhanced metabolic reactions, reduced muscle viscosity, increased extensibility of connective tissue, improved conduction velocity of action potentials, etc. - are obtained during the first few repetitions of an exercise. If a moderate or higher repetition range is used, the first few repetitions of an exercise warm up and prepare the muscles and joints involved for the harder reps later in the set and a separate warm up is not required. Additionally, each exercise performed helps prepare the muscles and joints for subsequent exercises they’re involved in.
I do not perform a warm up for the majority of exercises in my workout, and do not have the people I train warm up for their workouts with a few of the following exceptions, and no one has been injured as a result. Like most aspects of exercise, whether to perform a warm up or not depends on the individual and the specifics of the workout being performed. › Continue reading
Experiments With Rest-Pause Training
Background
For those unfamiliar with the term, rest-pause is a method of resistance training where a brief pause is taken between repetitions. Some variations involve a pause between every repetition of a set, some involve pausing between reps or groups of reps to enable the performance of additional repetitions after muscular failure has been reached. The rest-pause between reps is typically between 5 and 15 seconds, and some variations start lower and increase as the set becomes progressively harder.
Rest pause is not a new method of training, or even a relatively recent development. Peary Rader wrote about rest pause training in 1946 in one of his Iron Man training courses, The Rader Master Bodybuilding and Weight Gaining System, and Bob Hoffman wrote about a method of rest pause he called Muscle Contraction with Measured Movement in 1962 in his Functional Isometric Contraction - Advanced Course. There have been numerous variations since then, some of the most popular being the 20 rep breathing squats popularized by Randall Strossen in his book Super Squats, Mike Mentzer’s version from High Intensity Training the Mike Mentzer Way, and Dante Trudell’s “Dogg Crapp” training method. › Continue reading
