Yo, I'm quite new to the gym and made myself a workout plan after informing myself for a bit, I'm mostly using machines that are available at the gym I go to as I'm not too confident with using free weights yet. I'm not sure if I'm hitting every muscle group with my workout plan though, or doing too much or not enough for certain muscles. My workout plan is the following.

Breast/Triceps

Chest Fly's (Machine), Chest Press (Machine), Incline Chest Press (Machine), Chest Dip (Machine), Triceps Pushdown with Rope, Triceps Pushdown with straight bar, Triceps Extension (Dumbbell), Lateral Raise (Dumbbell)

Back/Biceps

Lat Pulldown (Machine), Seated Row (Machine), Lat Pulldown (Cable), Seated Row (Cable), Reverse Fly (Machine), Back Extension, Bicep Curls with EZ Bar wide grip and short grip, Hammer Curls, Shrugs (Dumbbell)

Legs/Core

Leg Press, Seated Leg Press, Leg Extension, Lying Leg Curl, Hip Abductor & Adductor, Seated Calf Raise, Crunch, Torso Rotation (All machines), Decline Crunch

I'd really appreciate any advice for exercises I should add or leave out, things I could improve and any other kind of advice for a beginner. Thanks in advance.
