As part of 5/3/1 I did a Boring but Big session of 5 x 15 at 52.5KG. (As per T NATION | Training Lab)

There will be two more of these sets this cycle.

I ached the next couple of days which is to be expected, but today's workout (3x3 squats and BBB deadlift) was a little 'flat' and a bit of a box-ticking exercise rather my usual effort at the gym - I'm usually looking forward to it on the drive there!

Is it likely I'm still recovering a little after 4 - 5 days?
