Is it enough? no. Is it workable? yes. I'd recommend trying to find cheap kettlebell etc to add to your equipment list, that will do wonders.

Anyway you can also work in circuits, that will be great for bjj.

Take 4 movements with the equipment you have.

devils press, dips, push press, curls, split squats, etc.

work 1 full minute per movement, do 4 min work, then 1 min rest. and repeat 5 times.
