The bare minimum?

I like,that I am back into my working-out-healthy lifestyle again. I enjoy going out to the gym almost every bight and get my workout done, and still, I feel like it’s not enough. I sometimes feel like I’m just doing the bare minimum, that I don’t push myself hard enough. I guess is the problem with not having a gym-partner or being part of a class. I want to do more, I would love being part of a class or maybe get into CrossFit, or similar. Treat it more like an actual sport and train like so. Do better nutrition and more healthy choices than the ones I have now. Maybe a full transformation of sorts.
