For the first few weeks, the sets were only done once.
I won't be able to add the third reps for another 2-3 weeks though.
I have been keeping it slow and steady over these past weeks, and that has been the secret to not getting overly sore muscles or stressed out joints.
Once I get the third set into the routine, adding weights to the ankles will be the next step.
I know that two pounds on each leg doesn't sound like much - but man they are hard to maneuver around in.
I am actually looking forward to using them though - that's a first!
