For the time that remains and for those of you who are just arriving here after having listened to the live-stream, I still have a special goodie... have you ever pondered over the following question:
How much can you achieve within 10 weeks of training?
|Even if you have already decided on a certain type of training, for example HIIT, you will have to adjust your routine to "Make HIIT a HIT" read Part I and Part II of the eponymous series and learn how to turn a HIIT workout into your HIIT workout to avoid overtraining and maximize its efficacy (learn more)|
The previous paragraph should have made it quite clear, compared to the (overweight) beginner, an advanced trainee must invest much more thought into his/her diet and exercise regimen. That real intermittent fasting would probably be a better alternative for him/her than the "buffered every other day fat" has already been mentioned in yesterday's SuppVersity Article, but what about the exercise regimen?
Working out for fat loss and conditioning - Crossfit rules!
|Fast paced high intensity workouts are gathering more and more momentum even outside of Crossfit gyms. Some of them may look somewhat "Jane Fonda", but as a previous review of the workout DVDs Insanity vs. TurboFire revealed, even hopping around in front of your TV set is more productive than the fat burning zone on the treadmill in next to your sofa (learn more)|
According to the results of a soon-to-be-published study from the Ohio State University Health & Exercise Science in Columbus, Ohio (Smith. 2013), there is no question that this would be a Crossfit-esque workout - or, as the scientists refer to it, a crossfit-based high intensity power training (HIPT) program, they describe as follows:
"[...] a crossfit-based HIPT program using basic gymnastic skills (hand- stands, ring, and bar exercises) and traditional multiple-joint, functional, resistance exercises (squat, press, deadlift, Olympic lifts) performed as quickly as possible at a high intensity (low repetition, high percentage of 1-RM)." (Smith. 2013; my italics)The 10-week program was varied so that some exercises were performed for a best time, and others were performed in the “as many rounds as possible” style (AMRAP; for a little more versatility check out Adelfo's EDT-CrossOver training) within anything from 10 to 20 minutes.
While there were no prescribe recovery times during the strength/skill portion of the exercise session, the WOD portion of the session did not allow for any real "rest" between the sets, as all the exercises were to be performed as quickly as possible.
Wow, who survived that? - Good question, indeed!
Only the fittest survive: Please do me a favor - If you are the aformentioned overweight person who's still carrying around another guy/gal's weight as body fat, don't even think of crossfitting, if you don't want to end up like 9 of the 11 dropouts (the study started with 54 participants), who retired willingly due to overuse or injuries, ok?I guess you won't be surprised to hear that the 23 men and 20 women who survived and of whom the scientists state that they were "spanning all levels of aerobic fitness and body composition" were actually the typical already reaonably fit Crossfit clientele of whom Smith et al. somwhat awkwardly point out that they "had already been following a 'Paleolithic' type diet prior to and following completion of the training protocol." In other words the "levels of aerobic fitness" the participants spanned ranged from the untrained yet 100% healthy male with a VO2max of ~35 ml/kg/min to the hardcore crossfitter with a starting VOMax of >50ml/kg/min - the aforementioned heavily overweight and thus by now average (see "Obese is Going About to Become the New Normal") Westerner was yet not part of the study population.
Still, the presence of subject spanning the divide between "just healthy" and ripped and well-conditioned is in fact what attracts me as the author of a webpage that's dedicated to anyone ranging from those who just want to be / get / remain healthy and look not all-too shabby in front of the mirror to those who are looking to max out on their own physical performance and appearance. Long story short: The data you see in figure 1 is relevant for all of you. Even if you are still a couple of inches away from matching at least the initially criteria, you will sooner or later arrive at a point, where you'll find a representative counterpart of yours among the subjects of the study at hand.

"To our knowledge no research on the aerobic benefits of HIPT has been conducted. HIPT focuses on high intensity resistance training usingmultiple joint exercises, with little to no focus on traditional aerobic activities. In spite of this, our results show that this type of training also provides aerobic and body composition benefits. Theincreased aerobic capacity of the subjects in our HIPT study were similar to those found in past research (Tremblay. 1994; Burgomaster. 2005). Based on the results presented here, individuals of all fitness levels and either gender can realize body composition and aerobic benefits from HIPT. Given that our subjects were following a Paleolithic diet, we cannot relate all of the observed weight loss to HIPT training. However, HIPT and Paleolithic diet in combination could be used to promote positive changes in body composition."Now, all the scientists write is unquestionably true (also the part on the "paleo diet", as long as it is not very low carb paleo, cf. "Carbohydrate Shortage in Paleoland") and still, for me there are two things Smith et al. don't mention in the paragraph cited about and these are (A) the sex differences in terms of the VO2Max gains (maybe a result of the fact that women are not the ones who would otherwise do HIIT-esque workouts (=aerobic training at high intensities), so that the new stimulus will yield a greater results and (B) the fact that Crossfit is a workout regimen, from which even those benefit who are already fit and lean (keep in mind that the 16% in the lean group are for men and women, so that is lean!).
Bottom line: Crossfit appears to be the high intensity workout regimen which can help experienced trainees to make the transition from lean to ripped!
|Want to do some more aerobics but also stick your classic weight lifting routine and just add cardio in? Now you are asking yourself, when this would make sense? Before, after or in between? Is that's you, go back in the SuppVersity archives and learn more.|
The "gifted ones" are in fact rather the ones who are often literally accused of being "genetically gifted" by accusers who simply don't take into consideration that it is above all the epigenetic priming of years of high school, college and other sports that renders them ostensibly resistant to the "obesity virus".
If you are still infected with the obsisty virus and have just found your way to physical culture you hardly qualify as one of those individuals by whom the original Crossfit workouts were created and are therefore certainly not among those people for whom these metabolically and technically demanding workouts were and still are designed.
If you do "qualify", however (and that is nothing you have to be born wirth, I myself once believed that I just did not have the genes to see my abs), cross fitting could fit in particularly well in your "beach-ready" plan, of which I'd hope you are already thinking about... I mean, spring is less than 3 weeks away (click here to learn more about setting up a workout routine)!
Addendum: Since I got several people asking for the lean mass changes, I thought I'd mention that there was a +1kg increase in lean mass in men and women. Unfortunately the scientists don't provide differential information for lean and heavier subjects, but if your body fat percentage decreases you do at least have to lose much more fat than lean mass and since there was no dieting involved, I bet the lean guys and girls did not lose any muscle..
