What do you guys do for exercise that keep you at your best?
Weight lifting, sprints, jogging, and power walking. Weight lifting is great for the leg muscles and helps maintain two point. I find parallel squats to be the most helpful. Sprints are great cardio; run full out for 50 yards, catch your breath, and run back. I do this around 10 times. Jogging is nice for endurance, as is power walking. Also, running up stairs is good for cardio and leg muscle.
Stretches are important. I stretch every night to keep myself flexible and supple. It minimizes aching in the saddle and keeps you from pulling muscles. What kind of diet do you maintain?
I eat what I want; I just try to eat small amounts of it.
A slice of cake is fine if it's just a slice, etc. I try to stay away from sugars and red meat, but otherwise my diet isn't very controlled. Any special vitamins or routines?
I walk every night and stretch every night. This is important, because if I don't do something constantly, I fall out of habit. I do sprints at school during PE and lift whenever I have access to free weights.
I also ride daily, weather permiting. 25% walk, 50% trot, 25% canter. Sometimes with less canter and more walk, depending on how my horse and I feel that day.
