Anyone not willing to give Greg Nuckols' Bulgarian Manual routine for squatting a solid try for 3 months is out of their mind.
Downloaded and reading now as my legs need some serious growth stimulus, thinking of continuing HST for upper body AM (6/7 days per week) and using Bulgarian for squats (PM) for 4 or 5 days per week with deadlifts on the other days - obviously you have enjoyed it and there appears to be quite a large increase on your 1rm!!
Just done a bit of catching up on your log after a lengthy absence. Well done, that man! Some great recovery training. And now PRs in your squats and a plan to squat 6 days a week, which is obviously very pleasing to my ears, virtually speaking. Rock on.
