In general.....you should deadlift more than you squat and squat more than you bench. How much is going to depend on your own biomechanics.
Of the 3 the squat is the most technical lift, the most affected by limitations in mobility, and the most affected by other outside forces (shoes, belt, etc).
Runners tend to have poor ankle mobility which will affect how wide they need to setup in order to hit depth (wider).
Runners tend to have poor hip mobility (tight hamstrings) which will affect if they can even hit depth at all without the pelvis tilting (butt wink).
While you work on these mobility issues (stretch, foam roll) you can work around them by doing low bar squats, taking a stance slightly outside shoulders, with feet pointed outward (30 deg), you could also use squat shoes or use heel inserts (up to 1/2in).
Also anyone going heavy (85% or higher....so 5 reps or lower) should be using a weightlifting belt when squatting. For no other reason than it makes it easier to keep a tight torso. It’s like an extra set of abs. Use it once, properly, and you’ll never go heavy again without it lol. The same goes for a shoe with a slight heel. And if you can, try it to lift in squishy curved running shoes. Your squat will thank you.
