Can anyone recommend some good HIIT routines? I only have access to treadmill/cross trainer/spinning bike.
I'm probably about a 5/10 atm in terms of cardiovascular fitness.
Also, on a related note, is HIIT the quickest way to make cardio gains? If so, how many sessions a week should I be doing (currently do 2-3 weights only sessions per week).
Thanks.
