Maybe, but on the other hand, if there was a major re-injury and you have been prevented from squatting for some time, going right into squatting very seriously on-cycle might be looking for further trouble.
I would rather be confident, based on some significant amount of pre-cycle training that went fine, that I would be able to handle the serious work on-cycle.
A particular psychological danger – which I’ve fallen into, though fortunately not with too-horrible consequences – is that due to being on-cycle and feeling “This has to be done NOW” judgment as to when to back off, that the program cannot be followed because of nagging problems getting worse and getting right on the edge of substantial injury, gets impaired. Nope, gotta bull through. There can be much more tendency to this on-cycle than off.
So it would be best to have undergone, not a trial by fire, but a trial of some serious and successful squat training beforehand so as to be more sure it can be done on-cycle.
