If you want to get technical squats develope all 4 heads of the qudriceps and is a mass building excericise for the entire lower body. To help strengthen your squat you would do a few different excerecises such as...HALF SQUATS... FRONT SQUATS also depending on how you point your toes what part of the leg your working the most, so you really cant compare the 2 since the legs are so much of a larger muscle.
DIPS...PURPOSE OF THIS EXECISE IS TO DEVELOPE THE THICKNESS OF THE TRICEPS ESPECIALLY THE MUSCLE AROUND THE ELBOW.
Execices that dvelope that part of the muscle are
Lying trceps extentions
Dmbell kickbacks
dips behind the back using a bench. as well as a couple others.
By incoroprating these into your tri routine you will see the number of dips you can do move up dramatically with the proper intensity and training as well as diet.
First of all i didn't went technical but your explanation was based on what science/technique?
Weren't you the one saying that dips are the upperbody squats? Won't you wonder why that is?
To getting good at squats you speak of front squats and half squats, which are squats variations... with same logical idea doing half-dips and assisted dips and yes the dips between benches will do the trick you wanna know why...
Dips work more that just triceps... they work chest, shoulders, rotator cuffs etc and you come talking about dumbell kickbacks and skullcrushers they don't even overload the same strength curve and points.
And now let's get to our Bruce here: he is a relatively large young boy who wants to lose weight, who can do dips but has trouble with most his lifts, has a true beginner do you think he needs anything else than squats, deads, overhead presses, pullups, bench presses, dips and some other compounds?
Ok if he couldn't do one single dip i would recommend declined close grip bench and CGBP why because both of them overload the same muscle groups that dips do only to a bit smaller degree nonetheless they are multi joint exercises but no, i repeat NO ISOLATION MOVEMENT LIKE KICKBACKS AND SO OR ANY CABLE EXERCISE WILL DO IT. And even if you did these in the same routine you would be overtraining and killing your tris.
But anyway do a search for yourself and you will find that what i'm saying it's true and the best strength coaches in the whole world would flame you for those statements..
