Ever heard the phrase "Too good to be true?" well doesnÂ´t it strike you as odd that after centuries of athletes training with cardio, it has now been discovered that you can achieve the same or better results in JUST 10 MINUTES!! (infomercial voice) Seriously, someone back in the last couple of milleniums should have stumbled on HIIT if it really were the holy grail of cardiovascular efficiency and efficacy.
Seriously, whats with all the anti-cardio stuff? Seems like if you do more than walk from the bench press station to the water fountain your biceps will catabolize away or some such nonsense.
HIIT is better for a fat loss blitz? Yes
Training like a marathonian isnÂ´t optimal for muscle building? Yes
BUT, being honest here, how many of the T Nation readers are professional bodybuilders whose living depends on being at 100% of their muscle and definition peak?
Is it really sensible to completely skip cardio because it purportedly can make you gain 20 grams less of lean muscle mass, and forgo all of these benefits it DOES give?:
- Increase in exercise tolerance
- Reduction in body weight
- Reduction in blood pressure
- Reduction in bad (LDL and total) cholesterol
- Increase in good (HDL) cholesterol
- Increase in insulin sensitivity
- Promotes high quality sleep (recovery is important for muscle gain too)
- Improved immune system
- Lower resting heart rate and recovery during exercise
HIIT and other kinds of "fast cardio" do not give the same results, just as low rest high rep weight training does not give the same results as low rep training with long rest. The heart produces different adaptations to HIIT and lond steady rate cardio, I recommend reading "Ultimate MMA Conditioning".
I probably will be moderated away or ridiculed by forum members, but I really think this anti cardio trend is doing a disservice to the health and results of many readers.
