I keep hearing I'm supposed to be smiling between sets of intervals... but the most I can muster is a pained grimace. Should I reduce my intensity? reduce duration? increase time between intervals? Or just grimace away?
My training typically consists of the following:
- on elliptical trainer (too much knee pain to run)
- flat out for 30 seconds
- recovery pace until heart rate drops back below 140
- repeat
I do as many cycles as I can over 20 minutes (about 7). Each set gets longer as my heart rate climbs. Flat out my heart rate gets to 175-180.
I have had amazing gains in fitness using this protocol twice a week for the past 4 months (when I started I could only do 2 cycles). So I find it's working. But no way am I smiling.
So should I just keep at it or tweak it? What are the benefits of dialing it down a bit? Thanks.
