Just curious what kind of cardio everyone does either Offseason or precontest?
I typically do HR at 150 for 30 minutes 3-5 days/week, but I have been thinking about adding sprints/HIIT to really increase my cardio ability
Creation,
I have messed around over the years with HIIT training, long duration cardio training with a lower heart rate, spinning, and every possible combination of time/intensity.
I am convinced that for maximum fat loss, cardio conditioning and no muscle loss, HIIT is the only way to go. Regardless of pre contest or off season.
I'm not suggesting you do this, but I do two 20 min HIIT sessions/day.
If I was to only do one session, I would do what you do, 30 mins, but change it to HIIT.
If using a treadmill, use elevation only, not speed to increase your HR.
If using bike, same thing, increase your HR by increasing the resistance.
If using step mill, use step speed.
From my own personal experience, I do not like eliptical motion and feel I get more benefit from any of the other three choices.
After a 1 min warm-up, go at it. I think your 150 HR should increase to about 160 during the difficult phase. But let it lower to 115-120 during the rest phase. I do my am session with one minute intervals and my pm session with 30 second intervals. I do a 1 minute really easy cool down at the end of either.
I find it difficult to use the treadmill with the 30 second intervals because it takes too long to get the incline up to where I need it, that's just the nature of how the treadmill operates. The bike or stepmill/stairmaster is almost instantanious regarding level changes, so I prefer them most.
There are many who believe that cardio training in the off season mode should be avoided because it may sarifice muscle. I would agree with that theory if someone was doing 90 minute sessions 6 days a week.
HIIT training will only increase your muscle building abilities because it will increase your recovery rate, thus allowing you to train with more intensity and less rest. Plus HIIT training will keep you in a fat burning mode long after you're finished.
All this is based 100% on my own personal experience. Although I have read many studies regarding this that support this, many will still disagree.
That's OK. But if you're curious, give it a shot. I think you'll be pleased with the end result.
BTW, check out my THINK TANK thread. This is the kinda stuff talked about or just ask the same question on my site, and see what kinda feedback you get from other guys, with lots of time in the trenches as well.
Peace,
