Looking for advice

Howdy everyone,

I recently started going to the gym with the goal of getting in shape and being overall more healthy. I’ve changed my diet and have been eating much better, but feel like I’m not maximizing my workouts and am looking for any advice or tips. Thank yall so much.

I currently do a three day split. Legs and core one day, back and biceps, and chest and triceps.

For legs I’ve been doing leg press, hack squat, leg curls, leg extensions and calf raises.

Biceps I’ve been doing dumbbell curls, preachers, and incline curls. I dont really have a set routine for back and could use the most advice there.

For triceps I hit two tricep machines and do tricep pull downs and over head triceps with cables. Chest I do incline press on the smith machine, chest press, dumbbell bench press.

While I have been feeling the workouts and being sore the next day, I feel like I’m not maximizing it.
