    Perfect Push Up vs Regular

    Interesting study done:

    Not terribly surprising, but the Perfect Push Up seemed a bit more promising compared to say the shake weight.

    Probably because compound pushing tends to have people working harder than accelleration/decelleration that the shake weight relies on.

    That said, much like shaking any weight, you can get UNLIMITED RESULTS if you simply shake it fast enough. Of course, it's incredibly hard to measure progress that way, which is why simply lifting heavier weights and doing separate bicep/tricep exercises is what people do.

    Waiiit, here I am going to post the study quote...

    http://www.nsca-lift.org/AllNews.asp?news=1493 (url is fine bro)

    Manufacturers of Perfect·Pushup™ handgrips claim enhanced muscular recruitment when compared with the conventional hand-on-floor push-up exercise. Electromyographic (EMG) data were recorded using surface electrodes from the right-sided triceps brachii, pectoralis major, serratus anterior (SA), and posterior deltoid muscles during push-ups performed from 3 different hand positions: (a) shoulder width, (b) wide base, and (c) narrow base (NB). Push-ups were performed under 2 conditions: (a) standard push-up and (b) Perfect·Pushup™ handgrips. We recruited 20 healthy subjects, 11 men (24.9 ± 2.6 years) and 9 women (23.8 ± 1 years). Subjects completed 3 consecutive push-ups for each hand position under both conditions. Push-up speed was controlled using a metronome, and testing order was randomized. We recorded peak EMG activity for each muscle during each of the push-ups and normalized EMG values by maximum muscle contractions (% maximum voluntary isometric contraction [MVIC]). Electromyographic data were analyzed with 3 (hand position) × 2 (condition) repeated-measures analysis of variance with a post hoc Bonferroni-adjusted simple effects test to detect significant position effects for position by condition interactions (α = 0.05). A push-up required considerable muscle activation of the triceps brachii (73-109% MVIC), pectoralis major (95-105% MVIC), SA (67-87% MVIC), and posterior deltoid (11-21% MVIC) whether performed using the conventional hand-on-floor position or the Perfect·Pushup™ handgrips. The NB hand position was most effective for preferentially activating the triceps brachii and posterior deltoid muscles. Based upon EMG activation from 4 muscles, the Perfect·Pushup™ handgrips do not appear to preferentially enhance muscular recruitment when compared with the conventional push-up method.

    Youdas, JW, Budach, BD, Ellerbusch, JV, Stucky, CM, Wait, KR, and Hollman, JH. Comparison of muscle-activation patterns during the conventional push-up and perfect·pushup™ exercises. J Strength Cond Res 24(12): 3352-3362, 2010.
    I bolded for emphasis. POSTERIOR deltoid for pushups? Wtf. I thought it might be a mistake but they wrote it twice...

    Pretty certain that glenohumeral flexion or transverse flexion is performed by the ANTERIOR deltoid. How confusing...
