I do HIIT and tabata style HIIT. There are really some amazing physical benefits when intense cardiovascular training is added to any athletic routine. More efficient nutrition partitioning, enhanced vo2max, enhanced lactic thresh hold. Two of the more important effects to look at would be the increased levels of glycogen and increased efficiency in glycogen usage.
I do cardio/conditioning 3x week. Pulling sleds, stadiums, and treadmill (LISS). I perform them on my off days as part of my active recovery. I personally think cardio is a good thing b/c your body will be more efficient when oxygenating itself and when trying to lift heavy weight you body will need to be able to oxygenate muscle fibers as quickly as possible.
To much cardio will hinder your strength training so you don't want to overdo it.
I havent done any cardio in a year or so , Damn I get tired walking from my car to the house. What is Cardio exactly anyway ? I eat ,sleep, eat , lift , work ,then eat and sleep some more ...Cardio is over rated in my book ....Maybe thats why I get tired from walking in walmart or sweat thinkin about walking past the fridge ?
Moreso than for weightloss, cardio is important for your HEART! I know some of you don't care about your heart, but you should! I hate the fact that I get winded all the time now whereas I would never get winded 5 years ago. This is definitely from lack of cardio. I'm commiting to cardio to bring my health back. Everyone should do some type of cardio during the week. If you hate the treadmill, here are some other options:
1. basketball 2. Play with your kids outside 3. run laps in the pool 4. swim 5. bike or hike a trail 6. run on the beach 7. sex (in a postion that requires your stamina) 8. kickboxing/boxing 9. soccer (not an option for me cuz I hate that 3rd world sport) 10. Eat Celery
