My pony is pretty forward going ...except when lunging..
He plods round like a cart horse on the lunge or long lines. I have tried various techniques to get him moving with more energy including working on a smaller circler making it larger and bigger with transitions. Once back onto a reasonable sized circle he will go about 5 strides then go back to Mr Plod..
He is fully fit and has no reason to be so lazy...as that is what it is ..being lazy...If I took him out in the carriage or under saddle he'd soon wake up but in the arena he gets bored..
Oh I also work over poles, figure eights up the long and short side, deviations etc all to make it more challenging, but go onto a circle and he plods again.
Any suggestions big or small may help
Someone suggested ankle weights (padded) to make him pick up his legs but that sounds mean ..what do you think...
