I've had quite a few people ask about my gym. There are a lot of guys providing solid advice and it depends on your goals and your budget. My goals over the years have changed from preparing for competition to retaining strength and endurance (and a little competition).
There are only a few things that remain from my early gym. I've kept a lot of weight plates. They never go out of style. The same with Olympic barbells. For those of you that are inexplicably still curious. I had some especially good counsel in building this gym - an orthopedic surgeon who has helped teams from Atlanta to Boston develop their own gyms. I also had what most people would consider, an outrageous budget. Here's the key parts of my gym.
Rogue Monster Cave - this is the heart and sole of my gym. It's more than a power rack or cage. It has plenty of features, not the least of which are fully adjustable pulleys.
Rogue leg press.
Captain's chair - for abs, pull-ups, dips, etc.
Roman chair - back hyper extensions
Versaclimber and Concept 2 rowing machines for cardio.
Tons of free weights, both plates and fixed dumbbells.
Box jump - it's 40 years old but it still works.
And last but not least, motivational posters of Mike Mentzer and Rachel Mclish. They are still very motivational.
That's it, guys. Consistency is key. Jeff Cavalier from AthleanX is my go-to guy for advice on lifting (not diet) and he has youtube videos for everything. I recommend his worst to best videos.
