He also went on to say squating is a horrible exercise due to the stress and compression of the spine.
You already know what I'll say about people NOT involved in sports medicine who say such things
That statement alone would tell me right there that your chiro knows zero about weight training's benefits and only sees the "bad" in what uneducated folks still hold on to as fact.
Personally, I don't trust most chiros as far as I'd throw them - they simply aren't qualified enough in my opnion to really be able to make certain statements, if it causes any compression on the spine it's automatically "evil" to them. Just like the guy who was happy to perform treatments on my sister's 2-year-old son and claim that they were helping him in numerous ways (nevermind that my sister is an idiot for taking a toddler to a chiro...that's a whole different story...), but told my sister that weight training would be bad for her in any capacity despite having zero health issues that would make such a statement valid. Too many out there who think they're physicians and are far outstepping their boundaries to give poor advice - when it doesn't seem right, ask someone with credentials, it'll do you more good.
The only chiro I'd trust now would be Dr. Ken Leistner, but that's probably because he can squat 405 lbs. for a set of 20 at under 200 lbs. bodyweight
