But, I do want to share two good workouts I came across and enjoy. One is a dumbbell core workout for runners, and the other is a medicine ball core workout for runners. I didn't want to do any lower body core this week to let my legs recover from racing, and came across these two workouts - they are primarily upper body/core workouts.
I usually do the circuit three times through, using an 8 pound medicine ball or 8 pound dumbbell and increase the reps to 15-20 if I am feeling spunky.
Check 'em out. I do this all in my garage with a mat so no need for a gym membership.
If you have any favorite core workouts, I'd love to hear about them. Share away!
