I'm having a horrible time of keeping my heels down and forward when I jump. They always keep swinging forwards and causes me to loose my balance. It doesn't help that I seem to very easily get out of breathe and tired very quickly. I'm a very slight person, 108 lbs and even though I run every single day I always get very tired only 15 minutes or so into the lesson. I have weekly lessons only which I know doesn't help but I can't ride anymore than that because I have drive a long ways to get to my barn. My parents don't want me driving any more than once out there because of gas and such.
Any tips on my swinging legs and lack of endurance? Like I said I run every day for 25 minutes, lift weights, stretches and etc. I can't figure out why I'm getting so out of breathe.
