sPL/SE1> iM heel of hand position

Is it 'acceptable' to lift the heel of the hand off the floor during this iM?

 

I'm working on wrist mobility, and can just about get sufficient lean if the heel of my hands lifts off the floor a little, but I'm a long way from having my body parallel to the floor if I keep my hands perfectly flat.

 

 

Until the rest of mobility is correctly executed the modification you are asking for it's fine.
