I actually had to do a full physical exam before starting on the gym. I can also guarantee to you that the environment on my gym is perfect: no real bodybuilders or dumb people, just a bunch of people worried for their health. It's located inside a sports center that offers swim classes, soccer/basketball courts for rent and preactice, so the whole thing just puts you in the right mood.
Here are my current measurements:
174 pounds
24% fat
37% muscle
My current workout usually starts with a 10 min warm-up (jogging on the treadmill) and then alternating leg/lower body > arms upper body exercises. I start with the bigger muscles and work towards the little ones. Then I finish it up with some abs/core and stretching.
As I said before, I'm feeling good by trying to be there everyday and it has the added plus (for me) that I can skip a day or two and don't feel guilty. It's very easy for me to drop out of stuff if I don't commit, hence the need for me to do it everyday (and create this thread).
I should also mention that I'm regulating my carbs intake and lowering it as much as I can. I'm not on full keto, but pretty close, and should start seeing my fat go down in a few weeks (I've done it before and lost around 30lb with zero physical activity).
