I love gym people

I feel such affinity toward “gym people.” Now, I love Pilates and I do it practically every day either teaching or my own personal workout but I also need to get some cardio in there for my heart. I love going in and seeing everyone working so hard to feel good and fit, I almost shoot “YOU ARE MY CHOSEN PEOPLE!” Unfortunately that seems a little inappropriate so instead I just smile and get on the elliptical. What breaks my heart though is when I see people giving such a fantastic effort but sabotaging themselves at the same time. I’ll add here that I am NOT a personal-trainer and I like to only speak about my knowledge of Pilates (that’s what I’m schooled in after-all) BUT I’d like to share from my experience as a fitness person.
1. Please try to support yourself on the cardio equipment. I see a lot of people collapsed forward on the railings. If your body is that tired then you’re just stressing your body out.
2. Your abdominals are made up of layers of muscles that help you do a sit up, it is not your neck that should be feeling fatigued.
3. I don’t know much about lifting with the weight machines but I’m pretty sure your chin should never jut forward, your posture should look pretty good and you shouldn’t be throwing your limbs around without control.

Does anyone know of some good fitness website that could give some good tips for lifting and cardio?
