VO2 max

i mentioned earlier that i hired a coach, but then got super sick. so not much has happened with that. but this weekend i had my VO2 test. ("Fitness can be measured by the volume of oxygen you can consume while exercising at your maximum capacity. VO2 max is the maximum amount of oxygen in milliliters, one can use in one minute per kilogram of body weight. Those who are fit have higher VO2 max values and can exercise more intensely than those who are not as well conditioned.") it was intense, but super cool.

they hook my bike up to a trainer so i can spin and i warmed up for about 15 minutes. then i put on a mask. the mask has a tube that goes into some reader device thing that reads how much oxygen i am taking in and home much CO2 i am exhaling. but it also measure how much fat (v. carb) i burn per minute how much fat per calorie etc. it is cool because you can see how it changes as the amount of effort you give changes. you ride for about 15 minutes and they get you to your aerobic/lactic threshold, so they can test your VO2 max. so i was producing more lactic acid than i could clean out. and then they made me stay that hard for about 2 more minutes. i seriously thought i was going to die. it was so crazy. one of my coaches was there and she just kept telling me to go faster and not stop and all that stuff. and then for the last 30 seconds she wanted me to just really push it: give it all that was left. when i could was finally allowed to stop, i was totally dizzy.

now they are going to create a training program having me work out in these heart rate zones so that i can get better and faster. but the truth is, its just going to get me to exercise. so i am excited. i got all out of shape and blah, so i am hopeful that i will feel energetic and fast.

i should get my first workout plan tomorrow. i am super excited.
