On Monday the 17th, had a visit to my Doc, who explained that my low resing heart rate (54) comes from the blood pressure meds I'm on. He told me to lower my range of HR for cardio accordingly. So it turns out 110 or so is fine (I'm fifty years old)

On Sunday the 16th did Cardio 20 minutes at 110 HR
Leg press 5x10/100
ball crunches 1x15
back hyperextensions 1x10

Today, Tuesday the 18th Cardio 20 min at 111
rowing, 6x10 /110
15 ball crunches
10 back hyperextensions.

Thinking of adding lat pull downs to my exercises--anothe big muscle to move, plus it will help when I go back to surfing.
