The biggest benefit has been an improvement in my breathing: I take in deeper breaths. And my running posture has improved...much less slouching. Larry: I've got 6 pack abs after all...they're just hiding under an inch or so of 'insulation'! Hey it's Canada...we have to stay warm in the winter!
After stumbling around with a few planinkg variations, I came across the above video. It's Olympian Carrie Tollefson's planking routine. She's a world class runner so ... what's good for Carrie works for me. It's 5 minutes of torture but does it ever feel good after.
Until next time...
