I struggle with all the negative aspects of commercial gyms that Roosh listed. I need exercise to function mentally and spiritually, and going for walks and hikes isn't enough. I work out at a Planet Fitness that is full of undergrads and the temptations to stare and lust are great. What I really hate about Planet Fitness are all the TVs vying for your attention, many of them showing vulgar and violent television and movies. The distractions and the sensory overload is unbelievable. It's such an annoying aspect of modern western culture.
Completely get the gym as mental health extension. It's second to Church of course, but maintaining a physical culture and activity is crucial in health and also mental health as well ....So my suggestion firstly would be to become financially capable of having your own home gym in your garage. Might take some time or life changes but it's really important that you make a commitment to doing this if you want to try and avoid the temptation.
If you save up $2000 you can get a professional power rack, bar, bench and plates and horse stall mats and can do anything you need to with a barbell routine. A sled willl allow you to do upper body and lower body movement and can be had for $100.
With 3-5 k you can pretty much fill a two car garage with quality equipment and avoid the temptation all together.
You don't have to dump $10k in it like I have over the last several years unless you're really really into it for sports purposes (I do powerlifting) and have expensive tastes.
But... If you're gonna keep going to a gym, find something more in the "hardcore" Gym style. These tend to have less Thots and are more barbell/dumbbell oriented and less bootymaster machine.
For myself, I can't work out at a public gym at all with out having a lustful thoughts. When I was single I used to meet girls in the gym, all of that, and it was really not healthy for me in viewing my fellow person as an Icon of Christ....this became clear when I started dating my now wife, we worked out 1x together at a public gym, and I realized i couldn't do it anymore. I mean I have a gorgeous woman right in front of me and still my eyes wandered. It's probably because I struggle with the lust issues already, but 1x was all I needed to make me realize that was not an option anymore.
Now if I'm traveling and it's the only option I'll opt for a gold's or LA fitness if I can't find something reccomended in my powerlifting groups... But in general, all the big box gyms are going to push filth in both their tv presentations and the people (namely women) there. In general it is getting worse and worse. Last time I had work travel and used a n LA I felt like I had just been to a strip club with the level of vulgar displays of female anatomy.
Roosh is absolutely right. It's best if you avoid the situation all together. I used to not think it was a big deal but even in 5 years I've noticed a worse and worse trend.
Frankly I also find that, because I have certain goals physically in mind, a public gym usually is a distraction. If I'm spending 1/4 of my time watching thots how productive am I being in my work out routine and accomplishing my goals?
