The purpose of this study is to examine the change to the muscle activity from the serratus anterior(SA) of 5th and 7th, upper trapezius(UT), middle trapezius(MT) lower trapezius (LT), and pectoralis major(PM) when push-up plus exercise(PUP) is performed in four postures. 25 healthy, young participants performed various PUP convergence exercise(general posture, $90^{\circ}$, $120^{\circ}$ and BOSU). The muscle activity of the shoulder stability muscles was measured using a surface EMG analysis system during various PUP convergence exercise. One-way repeated-measure of ANOVA was conducted to comparison the activity of each muscle. There was significant difference in SA7, PM, UT, and MT (p <.05) during various PUP. The muscle activity of SA7 had a significance difference between PUP and $90^{\circ}PUP$ or BOSUPUP respectively (p <.05). The muscle activity of PM had a significance difference between $90^{\circ}PUP$ and PUP or BOSUPUP (p <.05). The muscle activity of UT had a significance differnce between $90^{\circ}PUP$ and PUP or BOSUPUP (p <.05). The muscle activity of MT had a significance differnce between $90^{\circ}PUP$ and PUP and also significantly difference PUP and $120^{\circ}PUP$(p <.05). These results suggest that general PUP can be a useful to improve to scapular stabilizer muscle in who has no shoulder dysfunction.
