OK, the butt cramp is better. So, I hit it hard tonight. I noticed on the first LT, about three minutes in, my heart rate dropped four beats. Sorry, no power meter. So, I bumped up the RPMS about 5. Heart rate gradually climbed. Second LT I hit harder. Keep my heart rate two or three beats under VO2 Max. the last five minutes, I added a couple RPM, heart rate slightly responded.
Take away - A couple RPM did not jack heart rate. Where as, A couple RPM could be the difference between staying in the front third and dropping to the back. If I drop to the back, I gotta be ready for yoyo. Just say no to yoyo!
Great work out!!! Gonna go easy tomorrow. Saturday, weather permitting, hit it with the 'Gades.
