On pullups—you can replace them with pull-up negatives. Jump up to the chin-above-bar position and lower yourself as slowly as you can, particularly towards the end of the movement. Let go of the bar and jump again. About the only thing this doesn’t train, that the regular pullup will, is the starting-from-a-dead-hang motion.
(This has the added benefit of eventually being able to do pullups.)
I also advise that between jumping pullups, you return to a faux-deadhang position (even if this requires you to bend your knees to fit under the bar). Again, you will get tired of jumping pretty quickly and then will start to rely on your arms and back.
