I spend a grand on a nice adjustable dumbbell set and a bench and went from 165lbs to 210lbs over the last 18 months with a combination of weight training and eating better. It’s absolutely possible to work out at home with the resources that are out there these days. I do miss some of the equipment at the gym but the convenience of a home gym is just too good.

I would point out that getting lean/shredded is not a function of the gym, it’s a function of the kitchen. You cannot out exercise a bad or even mediocre diet. You can use a gym to build muscle, increase flexibility, or improve cardiovascular fitness, but there’s no avoiding making changes to your diet if you want to decrease body fat.
