I know Steve and Kirk; they are both very intelligent and have a lot of great insight to share. Kirk is a PhD. and Steve owns Iron Sport Gym.
Kirk is a 105 Kg Pro Strongman and has also competed in powerlifting and OLY lifting; not too long ago he deadlifted 765 lbs @ 230 lbs bodyweight. Steve is a long-time highland games professional and is also a pro strongman, he has trained numerous athletes at his gym in Philadelphia.
This would be well worth the $75 for anyone who is within driving distance to Philadelphia (Delaware, Jersey, Pennsylvania, New York City, etc.).
