"Are you tell me I don't have to do cardiovascular exersice?" is a question I get a lot. No. You do. But cardio is only a side dish. The magic happens in your lifting or resistance training. Your muscle dictates your metabolism.
Don't get me wrong, I still do cardio, but it is never more than 45 minutes a day at most, and typically this is when I'm getting ready for a show. I eat clean and consistently. I lift weights and work on my muscle imbalances so that my body is muscularly efficient all the time.
Today I met with a gal for the first time who pointed out that there weren't any people on the cardio peices of equipment when she came in to Fuerte. She had been killing herself on the Howe St./Eastlake stairs, for an hour a day 4 days a week for a year and a half and not getting results. Her calves were killing her but she wasn't getting any leaner. It's always great to meet someone who is self-motivated, but just needs a little help on the educational side of fitness. Learning about 'your' body is the best thing you can do for it. When you know which one of your muscles are tight, you can stretch those muscles out so you can get to the muscles that are weak because they are never touched.
If you sit for the majority of the day, then you are more likely to have tight hamstrings, tight hip flexors, and a weak core. The best thing you can do is get your butt moving... literally! Learn to engage your glutes: you butt is the biggest body part you have! Use you core (muscles around your spine) and stop using your lower back. Once that happens you will stand up straight let alone use proper muscle. So let's get our asses moving:)
Sometimes it's just that neurological communication you need so that your body starts working properly.
