I either sit in half lotus, or 90-90 style stretch. When I started I had a hard time sitting like that for more than 10 minutes, so I had to change position frequently, but it's better now. I'd switch from sitting to standing ( dining room table + small coffee table). When I got really tired, I'd sit down and start slouching. I slowly increased my sitting time.
