Hi Les,
Sitting while doing 7 steps is fine, but one
should work towards standing. It will still work
regardless. I have read on here, somewhere a while
back that the 7 steps can be modified to standing
on both legs, the same as the other exercises.
I have done it this way a few times and it is good.
It is easier to focus on the energy, rather than
focusing on keeping your balance.
Hope this helps.
Love Gabby.
