I too had my first ever formal training session last Wednesday. I am also 24. I went up to the SHARK TANK in Rancho Cucamonga, CA. I got a private/closed session in with J. fletcher. It was mostly grappling, but damn, DyingBreed you are right, my cardio was hurtin'.
Is it smart to train with no insurance? That is the only thing holding me back. Why? Because I eat like a pig, am about 30-40 overweight, have Asthma(w/ no inhaler), smoke herb and the occasional cigarette, and honestly, I don't know if I'm a hypochondriac or what, but my heart beats hella' fast sometimes for no reason. (that worrys me)
I basically took the class because it fell into my hands. I went to get some food, poked my head in the shark tank, the guy asked me some questions, one thing led to another and the next day I had an appointment at 3:30. On my way home I was like, "What the hell did I just get myself into? I know my body ain't ready for this.", but there was no way I was going to back out. So I went anyway. At times I was struggling, feeling real dizzy and my heart was beating hard in my chest. After the sess. I went to the bathroom and threw up all the water I drank during the class.
I know, mentally, I have the creativity and knowledge do be really good in MMA/subGRAPPLING, But I often worry that I have done irrepairable damage physically and won't ever get my lungs back. It made me realise just how in shape these guys are.
Anyhow BenchWarmer, I'm glad to hear you started training and I hope you stick with it. Maybe one day we will cross paths and train together. Good luck and work on that CARDIO man, in the amatuer ranks you will have a huge advantage if you got the fuel. Train hard Bro'.
