I've got a 4 year old who's broke WTC but now we're working on collection and using our body and hind end. I need some exercises and advice on how to achieve that since he tends to giraffe out and get heavy on the forehand. He's lazy and doesn't want to use his body. I'm not expecting it to be acheived overnight and I'm ready to put the work in just need some help on how to acheive it. I've had a trainer tell me to only work him in a circle/half ring and the first time her youngsters go in a straight line is at a show but I feel like thats cheating. Any advice would be appreciated!
