You are lucky having your son for training partner. Always wanted that but he is into extreme endurance training etc.
That is cool as long as he is doing something for the body/mind.
None of that at my main gym . Funny shit though SD... T
I took all 4 of mine to the gym with me from the time they were 5 or 6. Now that the youngest is 18, they all still go, with or without me. It is really neat on the rarer and rarer days that all of them plus me and the missus are there at the same time.
