When asked about the ultimate minimalist home gym, the Beastie Boys' "Two Turntables and a Microphone" line popped into my head. Only I heard it as "Two Kettlebells and a Pull-Up Bar."
With that combination and a couple of accessories, you can forge a bulletproof physique ready for anything life throws at it.
When helping clients set up a home gym, we recommend getting a pair of adjustable kettlebells because you will have a whole rack worth in two square feet of floor space.
We endorse the Bells of Steel Adjustable Kettlebells, which are well made and from a Canadian Company. https://www.bellsofsteel.com/all-products/conditioning/kettlebells/adjustable-kettlebell/#a_aid=Livewild
