How can I practice keeping my knee open? I don't pinch with it but sometimes I can't use my heel because I have my knee on the saddle

No stirrups work.
Hi Sharon
You can try put you weight in the inside of the stirrups which means you can turn your toes out a bit so you open your knee and also try relax and a lot of people close their knee when they are not relaxed. You can also try no stirrups and relax almost imagine you are jelly and this will help open your knee
Hope this helps
