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
3×3 High Intensity Training Routines
3×3 is a high intensity strength training routine consisting of three circuits or rounds of three compound (multi-joint) exercises performed non-stop to emphasize cardiovascular and metabolic conditioning. Each of the three exercises targets different muscle groups, usually starting with the hips and thighs, followed by upper body pushing and pulling movements, to work all of the major muscle groups and allow for little or no rest between exercises.
A higher number of repetitions is usually performed for the first circuit, with the repetitions dropping for the second and third circuits. A typical repetition scheme for a 3×3 routine is 20, 15 and 10 for the hip and thigh exercise, and 12, 10, and 8 for the upper body pushing and pulling exercises. For example: › Continue reading
CrossFit
Over the past couple years CrossFit has been gaining popularity as a way of training for “functional” fitness or general physical preparedness. According to the CrossFit web site, CrossFit is,
“…a core strength and conditioning program. We have designed our program to elicit as broad an adaptational response as possible. CrossFit is not a specialized fitness program but a deliberate attempt to optimize physical competence in each of ten recognized fitness domains. They are Cardiovascular and Respiratory endurance, Stamina, Strength, Flexibility, Power, Speed, Coordination, Agility, Balance, and Accuracy.”
The program consists of constantly varying routines incorporating a mix of “functional” movements such as various gymnastic and body weight exercises, plyometrics, Olympic lifts and other compound/multi-joint free weight exercises, and activities like running, cycling and rowing performed for varying durations to target different metabolic pathways. Workouts typically last well under an hour, and the recommended frequency is six days on, one day off.
While CrossFit will no doubt produce results, the same or better results could be achieved more safely and with a fraction of the weekly time invested with a few modifications. Safer, more effective exercises could be substituted for the Olympic lifts, plyometrics and exercises performed in a fast or explosive manner. › Continue reading
