I Trained under an ex pararescueman for eight months at a gym called SOFwods. I knock it because it has no linear goal and the client- to- program not program to client training program. You can't peak 24/7. in my opinion you need to lose waaaaay more weight before you attempt even a scaled metcon. That's not being sarcastic. Me being mean: you have no business being in a gym with free weights. Stick to your nautilus.
You got one issue with your statement, 80% of what I've always done is free weights and I've never used nautilus equipment other than a few times over 15 years ago. The other 20% is wire weight for back rows, butterflies and a few other things. It's funny you want to say I have no business around free weights when you just started like 45 days ago yourself. Cool story bro!
