Only bodyweight. Its not a huge part of my workout, partially because I dont have the space for a setup at home or the time to get to a gym every day.
My only constraints are to not go over x lbs (enduro race car weight, the heaviest driver is 175lb) and to maintain endurance because it helps maintain focus for long stints in the car. Every other benefit is gravy but always looking for the best way to go about it.
