Well im applying free weights training as opposed to the gym, because you can mimic specific body movements used only on trials riding. plus you have freedom to experiment with different exercise techniques in developing more power to your trials muscles. for example, when im doing squats, or frog jumps with free weights, i position my feet/stance in my favored pedal stance position (left foot back, right foot forward pedal stance). nowadays, i increase the exercise challenge by using a pair of pedals and placing them on the floor in my favored pedal stance position, then imagine myself eyeing up a wall to sidehop whilst doing the squat movements. this usual technique, focuses the specific leg, hip, waist, and ab muscle groups to work harder and coordinate better, esspecially with the extra bar/weights on my shoulders. another method i tried was to duct tape my barbell to my bike handlebars, put a few weights on it and go out riding practicing backhops, pedalkicks, and manuals...i do this on my own at night of course. id do this for 30mins, rip the barbell/weights off, and try the same moves again. the bike and moves feel lightweight. A more convenient training tool/device i also use during private ride sessions is a POWERBREATHE (www.powerbreathe.com) or the latest POWERLUNG (www.powerlung.com). both devices strengthen your lungs to work harder during riding. feel the results within 3-5 days of use. spending £50 or £70 for a piece of plastic is a huge waste of money, but the results to your riding power within days is HUGE! Ps, Ryan Leech does power yoga. Bruce Lee used free weights to develop his speed and power to such extreme levels that he could high jump his bodyweight up 9ft, and could hold 170lb barbell weight with his arms out straight in front of his chest, elbows lock, and back straight. insane power for a small man whom weighed 165lb. imagine that power on a trials bike....
