金小根（Hyo Keun Kim,김효근1984年8月23日出生于韩国）是一位韩国BBoy，他赢得的许多头衔使之成为世界上最好的BBoy之一。他是韩国最好的街舞团队之一-Rivers Crew的成员，也是韩国全明星街舞团队Project Soul（一说为Project Seoul）的成员之一。
从学校毕业后他来到首尔，Physicx开始了他的职业BBoy生涯。加入Rivers Crew后，他在BBoy界赢得了很高的尊敬。
在UK BBoy Championship上，Physicx第一次表演了他独特以及令人难以想象的舞技并且赢得了个人solo的冠军，这使Physicx这个名字很快传遍了世界。整个世界都发现了Physicx背后的天赋。
他的动作超越了想象，有些动作甚至是Breaking界从未出现过的，比如他的标志性动作，waistbreaker（我翻译为碎腰，应该是下面那一张吧~我估计是这个动作，呵呵~错了莫怪~）和hollowback swing 整个BBoy界很震惊地看到他其它漂亮的动作，包括只用一次发力做出的16圈肘转以及spinning flags。
如今，许多新一代的bboy和bgirl都把他当作偶像，他也很受其他许多专业的bboy的尊敬。
参赛方面，不管是代表团体还是个人，Physicx都是许多世界级赛事的冠军。他最显赫的团体成就包括代表Rivers Crew出战的2007年R-16 Korea和BBoy Unit Korea冠军，代表Project Soul出战的2002，2004，2005年UK BBoy Championship冠军。代表个人参赛，他赢得了2004年UK BBoy Championship个人solo冠军。Physicx被选中参加2005年Red Bull BC One 16位世界顶尖BBoy的一对一斗舞。
评委经历
Physicx被选作许多韩国Breaking街舞比赛的评委，包括BBoy ShowDown。
Physicx发展和推广了一些Breaking街舞的技术和动作，这其中许多动作被认为是很有技术含量并且十分困难的。以下是Physicx开创的动作条目。
Spinning flag/'60s: A flag freeze that spins like a 1990, but with hand twists independent of body movement allowing for slow but dynamic rotation.
Inverse 1990 flagged/River's 1990 to elbow/forearm freeze Hollow 2000/flag 2000/River's 2000: A 2000 spin with the legs piked horizontally parallel to the ground. Physicx usually does one-to-two rotations average considering this is one of the hardest 2000's ever created.
Knee spin to airflares Air Walk/Kicks: Throwing himself into a handstand, Physicx continuously transitions from handstand to forearm to shoulder to side freeze and back again. He does it in a random order while kicking his legs in all directions; this makes for an impressive display of strength and balance.
Airflare 1.5/Air windmills into Darkhammers:Physicx drops into a windmill, but pushes himself up into airflare form and drops while spinning into another windmill and then transitions into darkhammers.
Waistbreakers: From an unstabbed frog freeze, he shifts either one or both of his legs straight and beside each other to an L-back, then to a full hollowback and to the L back in the opposite direction of the first. While he is doing the 2 legged variant, he shakes his body while shifting. The 2 legged variant is always done after his transition with kicks (see above).
Nike handhops into Hollowback swing: Starting by holding one leg and hopping on one hand, and later dropping down to a hollowback swing for an impressive yet quick move.
Gainer into Icy-ice: Gainer, landed, then immediate dive into a shoulder or head slide. The slide is usually half spun with an ending freeze if it is his older head glide variation.
Hanging Airbaby
Multi-bronco jumps into freeze: A combo of which Physicx jumps into a handstand then jump backwards into a backhand spring and finally jumps backwards again with a landing freeze.
Handstand UFO: UFOs that are higher that normal and are usually done after a footwork sequence.
Hangbaby Spin: Usually after another footwork sequence, Physicx does a hanging airbaby with legs closed that spins for a short amount of time (usually ended as a planche with legs closed).
Dropping Airflares: Physicx goes into air flare form, but instead of jumping from one hand to the other when his back is facing the ground like normal airflares, he drops down onto his back and rolls back up into his other hand, and continues this sequence.
Hand stand into popping elbow tracks
