Are free weight lines, shrugs, and lats pull downs enough for the back muscle

The muscles that make up your back incorporate your lats (which get from the upper arms down to your glutes), teres major, rhomboids, just as the center and lower portions of the snares. These muscles are generally utilized when performing back works out. 

There are two significant sorts of back work out: pulling works out (eg., pullups and pulldowns) and paddling works out (eg., twisted around BB columns, situated link lines). 

Pulling practices focus inclining further toward the upper and external lats just as the teres major. 

Paddling practices focus erring on the center and lower lats just as the rhomboids and center snares. 

There are numerous different kinds of lat practices too, for example, sweatshirts and straight arm pulldowns. In case you are needing to reinforce your lower back region, where the spinal section is upheld, then, at that point, you can use back augmentations and great mornings. 

Thus I would propose that you do practices from every one of the accompanying groupings (I've featured a portion of my undisputed top choices): 

• BB rowing = BB rows, bent-over BB rows
• DB rowing = DB rows, incline DB rows
• Machine rowing = seated cable rows, Machine rows (to remove the stabilizers), incline cable row from high pulley
• Pullups = pullups, chinups,
• Pulldowns = lat pulldowns, reverse-grip pulldowns, close-grip pulldowns
• Pullovers = straight-arm pullovers, straight-arm pulldowns (yes, considered a “pullover”)
• Low Back = stiff-legged deadlifts, BB good mornings (I don’t like to hug a weight plate because I want to keep my spine neutral for the longest time), back extensions

On a back day, choose at least one rowing, one pulling and one lower back exercise. And you will really lie cable shrugs for the upper traps.
