For easy speciality, I’ve tried these and liked them (this particular roaster’s not easily available in UK but I’m sure there’s similar). These were gifted but I’d buy more if I was going camping or staying in a hotel. Proper ‘speciality’ flavours with zero fuss.
Belt squats are a great alternative, even if a little tricky to set up. They don’t load your lower back the same way but great for the legs and maintaining a squat pattern.
I ride bikes.
