I have just completed the first 3 waves of the 5/3/1 and it went pretty well eventhough I have just realised I made a slight mistake in wave 3 I should have done 75%x5 85%x3 and 95%x1 instead I done 85%x5 90%x3 and 95%x1.
Nevermind I still got all the reps and more in the repout on the 95% but then again I did lower my working 1rm a bit at the beggining of the cycle.
I have been ill and took 9 days off in the third wave but when I returned eventhough I hadn't eaten properly for a week, lost a bit of weight and hadn't trained for 9 days my lifts were still good enough.

Squat
Wave 1, 103k x5, 110k x5, 117k x5
Wave 2, 110k x3, 117k x3, 124k x5
Wave 3, 117k x5, 124k x3, 131k x4

Deadlift
Wave 1, 146k x5, 156k x 5, 166k x5
Wave 2, 156k x3, 166k x3, 175k x5

Overhead press
Wave 1, 43.5k x5, 46.5k x5, 49k x8
Wave 2, 46.5k x3, 49k x3, 52k x7

Everything has been kept pretty much the same except now im doing 1 arm deadlifts x 10 each side on Deadlift day for my obliques and from now on on OHP day ill be doing wide grip pulldowns x10 instead of chins.
Time for Wave 4 now The Deload then after that Ill add 5k to the 1rm for squats and deads, and 2.5k to the 1rm on the Bench and OHP

Thanks Jonson
