I have just begun riding a stationary bike...been doing 30 minute sessions 3 times a week on my non-lifting days. Anyway while on the bike today, every 5 minutes i would crank up the intensity and resistance and pedal full speed for 45 seconds, then return back to my normal pace. I did this 4 times within the 30 minute work-out. Is this a form of HIIT? Also, im starving after i do cardio just like when i lift. Are protein shakes good for post cardio work as well?
Thanks in advance.
