It really doesn't take much to start your home gym with a few pieces of equipment and build up from there. We started our home gym when we were RVing full time from 2017-2019 with a few kettlebells, mats, weight vest, jump ropes and some mini bands. This got the job done and made us more creative in our WOD programming with limited equipment. A year later we added an olympic weight lifting set and pull up bar.
