Summary: October 2019 @mhguenther and I have the complicated #shieldlock conversation about maintaining your #concentrica while training for life and events. Mistress definition - a woman who has control over or responsibility for someone or something = a woman other than his wife with whom a married man has a continuing sexual or loving relationship In addition to doing amazing events, Mark is also the rucking coordinator for F3 Nation. He’s the guy who runs the F3NationRuck Twitter account as well as their F3 Nation Rucking Facebook Group. #56 in your program, but #1 in our hearts.
