Basically what's the difference? I do low bar squats but find it puts a lot of pressure on my elbows. A mate said doing high bar squats are better on the elbows but you won't be able to go as heavy. Do they target the same muscles or do each put emphasis on different muscles?
A high bar squat is characterized by higher placement on the back and a more vertical back angle. Low bar squat has the bar lower, on the spine of the scapula, and has a more horizontal back angle. Which one is better for you depends on your anatomical dimensions, goals, and which one you prefer doing.
Bc the back is more horizontal in a low bar squat and you sit back further into it, it contracts the hamstring more on the concentric portion and allows better recruitment of the posterior chain musculature, especially the hamstrings.
Bc the low bar squat has a more vertical back angle and there's not as much sit back there is less posterior chain recruitment so the anterior muscles must cover the difference, namely the quads.
It's important to understand both squat styles work both anterior and posterior muscles. The only difference is the "ratio" so to speak.
Elbow pain is very common in this game. Not every human body was not made to squat a barbell perfectly. I have the same thing you have and so do many others. There are a few tricks to help reduce it. The reason you're getting elbow pain is bc of pain referral where pain stimuli from one. Part of your body sends the signal that it's coming from another.
Bc your shoulders have to be pinned back, chest up, head back, and scapular retracted whole shoving a barbell back there, it places a great deal of stress and mobility demand on the shoulders. The pain from the shoulders is being referred to the elbow. It's not clear which nerve is the cause but the main ones that start in the spine and work their way through the shoulder and down the arm are the radial nerve, axillary nerve, ulnar nerve, median nerve, and musculocutaneous nerve.
1) a high bar squat will def help with this as the bar is higher on the traps and doesn't require as much shoulder mobility to keep the scapula retracted and back.
2) the wider you do your grip the better. Less pinched shoulders.
3) thumbs over grip
4) squat with a SSB, cambered bar, or buffalo bar rather than an Olympic bar.
