Also, following the advice from Jordan and other users I'm ditching AMRAPs for now.
I'm sticking with a GSLP A/B setup as it saves workout time, allows extra recovery, more flexibility etc but I'm going to step up the progression.
Sticking with 3x5 (no amrap) with faster increases on weights until I hit a few resets. Along with 'linear progression bulking' this should suit me for a little while. Adding 2.5kg to all lifts, 5kg to deads, until resetting then slowing progressions down a bit.
After this 'Greyskull SS Variant Program' I'll probs move to GSLP or TM for intermediate work.
I'd love to have a 150kg squat, 100kg bench and 180kg deadlift before that though! Not sure how achievable that is yet though!
