Cardio, cardio, cardio ad nauseum and other rants
Monday, May 10, 2010
Pardon me while I scream in anguish and agony but if I read another post saying that cardio is the answer to anything other than endurance and cardiovascular fitness I will go over the edge. "Burn more fat", "Increase your calorie burn" "break the plateau", "More is better; urban myth has more heads than Hydra. While cardio does have a place in every fitness programme it is not the be all and end all and only a person training for an endurance event needs to do cardio workouts more than two or three times a week and even those need not exceed thirty minutes if the intensity is high enough.
To warm up for weight training you do not need fifteen or twenty minutes on a treadmill, a set of twenty four count jumping jacks and twenty four count squat thrusts (burpees) will light the required internal flames.
Why do people alternate been strength exercises and cardio in the same workout going from one to another? If you make your strength workout a circuit workout you have no need to add a cardio portion. Contrary to the infomercials, over publicized "personal: trainers" selling DVDs adding a cardio component to a strength circuit adds about three to five percentage points to the cardio benefit obtained from doing a strength circuit without it. I am yet to be convinced that doing an aerobic dance routine with barbie dumbbells can be classified as a "strength" workout. I am now pronouncing a personal jihad against dumbbells under fifteen pounds in weight being used by anyone over the age of sixteen years since by that age the foundation of adult muscular strength has developed..
How many reading this rant accept the concept that a sixteen hour weekend course and passing a 100 question multiple choice examination with a score of 70 or better certifies you to be a trainer of any sort? Even if you are a certified high school physical education teacher you are expected to taking coaching courses in order to obtain a coaching certificate. Then many seem to be more prone to accept what the cousin of a friend found worked for them than to accept the findings of juried research. Anecdotal evidence has more creedence than research.
Enough of this diatribe for today.
