• .joelseedman_ahp Here I have athlete performing chaos band pullups with knee raise protocol which I highlighted several years ago on my website (article for chaos pullups at link in bio). Notice the 90 degree angles. Yep 90 once again. Why you ask???? Because 90 deg angles on most movements such as squats, presses, pulls, lunges, & hinges, represents the most effective & therapeutic stimulus not only for optimizing functional strength & hypertrophy but also for minimizing joint stress. Yes of course you can go farther but then it’s not longer producing the optimal training stimulus for the muscles and you’re also increasing the potential consequences.
Still don’t believe me??? Try this exercise using smooth mechanics without any bouncing while also maintaining maximal core activation, postural alignment, shoulder packing, & full body tension. Because you eliminate momentum & are forced to maintain high levels of spinal rigidity & perfect posture, you literally won’t be able to break 90 unless of course you sacrifice all of the aforementioned cues & important technique elements not to mention optimal osteokinematics & arthrokinematics.
In fact it really doesn’t matter if me or my athletes perform these with bodyweight or heavy loads, functional ROM terminates at roughly 90 deg every time. To go past this you’ll compensate in some fashion somewhere in your body even if its subtle (i.e. lumbar extension, internal rotation of the shoulder, crowding at the glenohumeral joint, forward head tilt, shoulder protraction & elevation, lack of joint centration & faulty activation patterns). To maintain maximal full body tension, posture, shoulder retraction & depression, braced core, neutral spine, & tight grip, you won’t be going past 90, not now, not ever. Case closed!
With that said the chaos pullup is one of the most effective pullup & lat exercises for blasting your upper back & lats while also cleaning up pullup form. 7 Reasons why its so effective I highlight in full article at link in bio. Also read more about 90 deg angles & eccentric isometrics in my book MOVEMENT REDEFINED at link in bio.
