Out the saddle, heels down! I normally shout this at the kids when descending.
Think light, be light. When riding over wet roots.
Let the bike roll and it’ll do the work. When you approach a trail obstacle and start to hesitate and pull the brakes.
Inside pedal up! Again shouted at the kids as they approach a berm.
Momentum is your friend. Much more sense than the usual speed is your friend IMO.
Just relax! Best used before a jump.
Spin to win! And cadence is king!
Up! Up! Up! Shouted at the kids to get out of the saddle when they’re approaching a small climb on the trail so they maintain their momentum.
