okay so i am doing a physics project on BMX biking….
and what are some positions to avoid when bmx biking so that one can reduce strees on their body?

and…. use for any trick ( any exampel of a trick) how would one position their arms, legs etc, to create teh highest jump, fartherse leap, just the most power, teh most efficent way to go about teh trick… any example is apreciated!!!
thank! *bow* bow*

Well the most likely position to emit strain on the rest of the body is the strong attack position. This is where the rider is stood up, knees bent and stif, arched back and arms bent and locked out from moving. This is used when wanting to pull a bunny hop, the rider would then just pull up with his locked arms and lift his legs up but keeping them on the pedals. To create the furthest jump the rider will be wanting to lean a bit more forward so his arms are going straight down to the bars, because his weight is mostly forward when he does a bunny hop he will go further forward. To get a pretty far jump the rider will be going a lot more faster and will pull up more with his arms to get that front end higher than the rear. To get the most power the rider will be stood up, arms a tiny bit bent and all his weight on his legs, when he pedals the momentum on his legs will get the bike up more speed and also he can push down on his bars and lift back up, that’s called pumping and is very useful to get that bit more speed when pedalling will be risky. The most efficient way to approach a trick is the attack position, arms bent, legs bent and a slightly arched back. This gives the rider full control of the bike and he just needs to shift his weight if he wants to attempt a spin or flip.
Hope this helps dude
