Starting fresh... advice, please?

I have
been a D-I varsity athlete for the past three years. I'm "retiring", and I want
to start planning my own workouts. My sport has required heavy
lifting/fast-twitch muscle workouts. I want to slim down and build up my
endurance. I have never really trained without a prepared workout plan from a
coach, as I've been competing in this sport for nine years and have always been
on a competitive team growing up.

I want to build up my running endurance, continue weight-training with light
weights (toning), and build a strong core. I'm good with eating when I
discipline myself, and I enjoy working out.

Oh, and I'd like to avoid joining a gym--costly, and I only have two months of
summer va-cay!!

So, where do I start?

THANKS!
For a schedule all you have to do is go to:
http://coreperformance.com/

and click on the one week free trial button
It is an INCREDIBLE site and it asks you what your goal, is and you could say
weight loss and it creates a schedule and meal plan especially for your goal and
height and age....
And, you can put in how much you are willing to do each day and for like 2 or 3
days a week and it'll make the workout more intense or less depending on the
amount of time. THe meal planning is also good because it gives you a healthy
diet and it helps you work towards your goal.it will give you all sorts of
exercises that could involve the equiment you have or you might not even need
them. It has vidoes of everything it asks you to do...so you don't have to worry
about doing it wrong. I am also a runner(only in high school but for X-Country i
am the girls' varsity captain) and i use coreperformance.com to help me build up
my endurance and it helps me a lot it gives me energy without fat...and i feel
great. So, try it...what do you have to lose? It's free for the first week....so
just give it a try...you'll love it!!!!And, if you decide to keep it is only
about 10 dollars a month, and it is definelty worth it!!!!!!!

Good Luck!And I hope you reach your goal!!!I'm rooting for you!!!!!
