If you read my emails and blog posts I'm sure you've heard me reference the name, Dan John .
His genius is in his simplicity of training. He says, if you care about being strong, you must be strong in these three movement patterns:
Picking heavy stuff off the ground (deadlift)
Lifting heavy stuff overhead (overhead press)
Carrying heavy stuff for time or distance (farmer walk)
Strong can be a very relative term. So here's it can be defined relative to you.
Men: Pull double your body weight from the ground.
Women: Pull 1.5x your body weight from the ground
Men: Lift bodyweight overhead
Men: Carry body weight for 100 yards
Woman: 75% of body weight 100 yards
