i have an olympic bar and plates I use for deadlifts, TRX straps (a must have!), some dumbbells, a collection of foam rollers, some stretch bands and a Revolution balance board. I can get some adequate strength work and a great core workout with this stuff.
I have a weight bench which I use every single day - as a chair - but i have not used it to lift weights in over a decade.
I did recently end up joining a gym for off season access to squats and some leg machines. I live 300 yards from a Planet Fitness and at $10/mo its a crazy great deal if conveniently located.
