lol, it looks like he got someone to help him with lighting and, like, not wearing a t-shirt with the collar completely worn out. well, good for him. uncanny timing for the subject matter, will watch today.
- track threshold
-- warm up
-- 6 x 5 min @ threshold (4:08, 4:09, 4:07, 4:06, 4:05, 4:05), 1 min walking rest
-- cool down
threshold for me, per the jack daniels VDOT calculator, is 4:12. so by that measure, these were a little too fast, especially the later sets. OTOH, heart rate was upper 150s to lower 160s on all but the final set, and breathing was never labored. had a hard time keeping consistent pace in the first few sets. felt like a real workout, i was tired at the end. upper legs a little sore and, oddly, my left hamstring and right quad are a little more sore than their counterparts.
