Your concern over back to back high intensity training is absolutely valid. However, consider that most coaches in the UK (Christie, Arnold and MK) are ALTERNATING high intensity training components. Additionally they are performing more sessions, more volume AND more exercises in the gym! On my template track sessions always follow a days tempo… Not perfect, but certainly a big improvement!
Muscle soreness from my program will be minimal because volume is so low and the exercises remain consistent. My weightlifters require more recovery because they perform the full versions of the lifts; more volume (attempts at maximum, flushing sets etc) and at a higher absolute intensity (since they are fresh for each workout).
During the peak competition period I recommend the athlete stops one set before maximum. This is usually sufficient to maintain 95% of strength without overly fatiguing the organism. During other training phases I don’t advocate formalised deloading weeks but intuitively allow lifters to ‘take the foot of the gas’ for one or two sessions if they are feeling jaded.
I’ve answered the question regarding women earlier in this thread..
