What's the *minimum* home equipment to be an effective supplement to hiking/biking/calisthenics for overall fitness? Is a bench and bar really needed or would a few dumbbells and a kettlebell, and the home version of TRX, be enough? (for an early 50's guy not aspiring to be ripped, just reasonably fit).
I'm presently a gym member so spoilt for choice on equipment. Not super into weight training, but most of my cardio is already out on the trail so majority what I use the gym for is in the weight room (I even - blush - have been using a personal trainer in recent years). As I get deeper into frugality (*), eliminating the gym membership is an obvious candidate (nixing the personal trainer is a no-brainer). But I am space-limited at the moment, will be moving later this year, and in general am looking to minimize accumulation of "stuff", so I hesitate to kit out a full "home gym".
* more for philosophical than needful reasons... I'm basically financially independent but lucky enough to have a flexible job that I enjoy so am still employed & accumulating.
