In reply to geebus:
you will lose weight by training inthe optimum zone and adjusting your diet to it. it depends what those kcals are made up of. a properly optimized schedule will have you longer in the functional zone than a binary one because you will be better recovered to be there.
i cant se why it has to be 7 days/binary: consider 1 x 7 days binary (rest on 7th), then 1 x 3 days another focus, 1 day rest, 1 x 3 days a third focus.
the point is to get enough time in the zones you want (including weight cutting) to really make progress, but scheduled also so you minimize injury and optimize function.
i am skirting you real question tho: same day weights/climb.
not generally, but at times specifically - on hard climb days sometimes use weights to antagonize, and on easy climb days sometimes use weights to spike stressor levels.
in another way, weighted stretches are useful IF done safely (or russian roulette if not...).
really, for losing weight in a climbing context long sets of relevant lifts done at low weight will likely be optimal - but will need smart programming to recover from and prep before.
note: a 10 day (or longer cycle) can still have rest days on the 7th, it just doesnt restart again after it.
