Preacher hammer curls are a legitimate, wrist-friendly way to train your elbow flexors, but they are not the brachialis specialist most lifters believe they are.
The bench does something real. The grip does less than gym lore promises.

Flip your hands over on a cable pushdown and the internet splits in half. One camp says the reverse grip tricep pushdown unlocks the medial head.
The other says your hands moved and nothing else did.
Below you get the form, the muscles worked, the evidence, and a straight answer on whether this belongs in your program.

You do not need a pull-up bar, a machine, or much floor space to train your abs hard. Seated knee tucks work on a bench, a mat, or the edge of your couch.
They train the rectus abdominis and hip flexors together by drawing your knees toward your chest from a leaned-back seated position, and they are the practical stepping stone to hanging knee raises.

You anchored a band to the top of a door, stood or knelt down, pulled hard, and felt the whole thing in your forearms. Your back never showed up.
That experience is close to universal with the banded lat pulldown, and it is almost never the band’s fault.

A supinated bicep curl is the classic palms-up curl, and it keeps more tension on your biceps than any other grip.
It is also the only common curl that trains the biceps’ second job: turning your palm up. Simple movement, real payoff.

You finish a set of rear delt raises, your shoulders are on fire, and the pump feels incredible. Then you check the mirror a week later and the back of your shoulders looks exactly the same.
Usually the effort is fine. What goes wrong is that your traps and upper back quietly steal the work from the muscle you are trying to hit.

Lateral raises should not click, pinch, or nag the front of your shoulder. If yours do, the scaption raise is the fix.
It is a diagonal raise done 30 to 45 degrees forward of straight out to the side, in the plane where your shoulder blade naturally rests against your rib cage.

Standard dumbbell pressing has a habit of handing the work to your shoulders, and if yours already feel cranky, benching turns into a chore you dread.
The dumbbell squeeze press (also called the hex press) fixes that.

The overhand bicep curl is a bicep curl in name only. Flip your palms from up to down and most of the work slides off the biceps and onto your forearms.
You might know it as the reverse curl or reverse barbell curl, and it is one of the rare arm moves where the biceps ride shotgun instead of driving.

One fitness site calls the weighted back hyperextension a glute exercise. The next calls it a lower back exercise.
Both are right, and neither explains why: pad height and spine position decide which muscle does the work, not the name on the machine.
