When to reach for it and when to move for it
Sit them in a circle and ask what they do when a hold is too far away. Collect the answers before you give any.
Static is reaching it with strength and position rather than momentum.
Dynamic is using momentum to cover ground you cannot reach.
Same problem twice, once as slowly as they can and once with momentum, then ask which suited it.
Follow with a jumpy problem and a slabby one, so the answer comes from the terrain rather than from you. Half the group and a coach on each, then swap, so both are running at once and the question gets asked of every athlete rather than of whoever is at the front of a line of ten.
Everything becomes a jump. Ban dynamic movement for one climb. Static is the harder discipline and the one that transfers.
They will not commit to a dyno. Lower the target. A dynamic move to a hold a hand's width away still teaches the timing.
