I deviated from HCT-12 and did 20-rep legs.
How many of you have ever done this? Holy crap...
I didn't actually do it with squats, but on the let press/hip sled (it's a knee thing).
I ramped up to a weight that seemed appropriate, then did two 20-rep sets.
Let's just say I had leg tremors/spasms for the remainder of the workout last night.
