BODY BY SCIENCE — VIDEO 1 (COMMON THINKING ERRORS ABOUT FITNESS & HEALTH)
Recently Dr. McGuff gave a brief seminar about the content in our book Body By Science at a book signing that happened to be recorded on video tape. I’m going to post this seminar as a series, covering different topics covered in the book ranging from “cardio” to “Whom Can You Trust?”
It is my hope to provide higher quality videos of this talk (and others) on this site in the near future. In the meantime I will upload these excerpts on Youtube.com and post links to the presentations here on this blog. The first one is up and (as always) Doug gives a masterful presentation of the material covered in our Introductory chapter. The link to watch this video is below:

In this excerpt, Dr. McGuff explores the true nature of cardiovascular exercise during a seminar he gave at a recent book signing. The realities of “anaerobic” and “aerobic” pathways and his concept of “Global Metabolic Conditioning” (the touchstones of Chapter Two) are examined in detail. Here is the link to Part Three:

In this video (taken from a recent lecture Dr. McGuff gave at a book store), Doug speaks about Chapter 3 of our book Body By Science, in which he details the Dose-Response relationship of exercise. Along the way he touches on the content of other chapters such as Enhancing The Body’s Response To Exercise (Chapter 6) and Tweaking The Exercise Stimulus (Chapter 7). Here is the link to this video:

In this segment, Dr. McGuff explains the proper role of strength training for athletes and contrasts it with skill training (an important distinction that we cover in great depth in Body By Science). In addition, he elucidates the supreme importance of strength training for seniors, revealing how it enhances both health and (to an amazing extent) functional ability. Here is the link:

At Nautilus North we’ve been experimenting recently with a “Done In One” workout that consists of three exercises (a Chest Press, a Pulldown and a Leg Press) that are performed for one repetition each. The idea being to load the muscle and have it move very slowly for one repetition (or, as happens sometimes, a repetition and a half) until the muscle groups involved have been fatigued or inroaded to the point where they cannot produce enough force to prevent the weight stack from coming down. To make the inroad deeper we’ve been using what would be considered light weights and it’s a fine line in that the weights must be light enough to effectively isolate the targeted musculature yet heavy enough to ensure a sequential recruitment of fibers takes place, resulting in failure being reached in approximately 1-2 minutes. As indicated in Body By Science, as one progresses in strength, it is sometimes necessary to reduce the volume of one’s workouts to a “Big 3.” This is one way of performing a “Big 3″ workout.
To this end, one of our trainers (Blair Wilson) is using this protocol and enjoying very good results. The global metabolic conditioning effect is phenomenal. I recently video recorded Blair going through his workout (this was his 2nd performed in this fashion) and also recorded his post workout response. As Blair is one of our trainers, the atmosphere was more relaxed and, of course, whenever a hard workout involving legs is performed it is mandatory that other trainers put the grab on the poor trainee’s aching legs as often as possible after the workout (I know, we’re not very nice — at least to our trainers).
Blair is a great guy and a terrific athlete. He recently returned to Nautilus North after three years in Australia where he worked for Sea World as one of the trick skiers in their ski shows. He’s an excellent barefoot skier, wake boarder, and accomplished at jumps. While he was in Canada he played “A” level ice hockey (an informal study that Blair did with hockey players is mentioned in Body By Science). Blair trains on average once every 7-10 days and typically performs a “Big 3″ workout. Here are the links to his workout and post workout videos:

AMY’S “BIG 3″ WORKOUT
Certain of our female clients at Nautilus North have agreed to our our video taping their workouts so that readers of Body By Science can see points of form, technique and proper breathing. Here Amy is put through a “Big 3″ workout under the direction of trainer Blair Wilson.
The protocol featured is the “Done In One” method, whereby the trainee attempts to inroad slowly and thoroughly so that he or she is literally “done” in “one” repetition. It can be used with a 30-seconds out/30-seconds back time signature or 1-minute out and 1-minute back. If the client still hasn’t inroaded to the point where the weight (which is deliberately set to be lighter than he or she would normally use) has overcome his or her force output, the trainer will encourage the client to attempt a second repetition (sometimes this works out out to be only one and a half reps, and occasionally two). This is just one way to perform a “Big 3″ workout but we thought it might prove helpful to female readers of our book. Here is the link to Amy’s workout:

TRAINING THE LOWER BACK
In our book The Body By Science Question & Answer Book Dr. McGuff and I devote a significant section to training and rehabilitating the lower back. As the lower back can prove problematic to some (by some estimates, between 75 and 85% of the population will experience lower back pain at some point in their lives), keeping it strong is very important and can go a long way toward keeping you in the 15 to 25% that do not experience such problems).
Dr. McGuff has put together a two-part video that will help trainees immensely in strengthening this important area of the body. In Part One, Dr. McGuff describes the anatomy of the lower back and what muscle groups we need to focus on with our training. In Part Two, he continues with his presentation, demonstrating three exercises that can be performed to strengthen the lower back for those who do not have access to MedX or Nautilus lower back machines.
