I have a problem with boredom when getting my cardio in, especially in the winter when I’m inside.
I train 3 days a week and “try” to get in 2-3 days of Exercyle, or treadmill work. In order to make these cardio sessions palatable, I break the sessions up ex: 15 minutes on the treadmill 4mph, 5 degrees incline (gets the heart rate up to about 120bpm); do a few machine exercises which take 10-15 minutes; back to the treadmill for another round of 15 minutes at 4mph, 5 degrees of incline.
Does it matter that I’m breaking things up in such a fashion, or do I need to plod along for a full 30 minutes with no breaks in order to reap maximum benefits?
High intensity stuff is not on my plate at the moment due to health issues.
