If you’re Nancy, Master Chief of the Quad Squad, sometimes straight weight just isn’t enough.
I could bore you here with careful, theoretical reasoning as to why adding chain to heavy squats is a nifty little trick to get you even stronger, but I won’t (because I’m sure I’ll end up doing it to you in the gym anyway). Instead I’ll say this: when you’re as experienced a lifter as Nancy is dynamic approaches like this matter, and can make all the difference in getting you better. As an added bonus, you’re also rewarded with looking like a weightlifting badass (although it’ll be tough to equal Nancy in this regard). It’s one of the perks that comes with being dedicated to your training as long as she has.
