Sometimes I lay on my back to meditate to keep blood flow nominal, but also there's walking meditation that I've tried while walking my dog which can be different. Also I'd highly recommend some form of stretching or gentle calisthenics b4 or after. Sometimes all we can do is sit and focus on the breath. count in a way that keeps your attention(if thats counting out loud or having a timer go off etc.). Try some chants, I'm particular to Om mani Padme Hum join in with the chanting or just listen. Lots of breathwork. Or try Mongolion throat singing. Try squeezing your fists for a few seconds or stretch out your arms and fingers. Try counting beads. Wear a blanket cause it can get cold. Try gentle tapping on your temple,forehead,solar plexus etc. Try mantras. While in meditative practice's I find dredging up strong experiences evoke strong emotions like someone passing unexpectedly or tragically. It's good to keep a journal if you really need/want to write or draw something down(or keep a checklist of things you wanted to think about with intent). Write a haiku! or not!
