Everyone here is going to have a different opinion.
Mine would be that (and it's only informed based on my own experience) you seem to be doing a lot of different exercises that aren't necessary if you do some lareger more dynamic lifts.

Leg curls, leg extensions, and leg press?
You'll probably be better served to do squats and deadlifts instead (GET GOOD TRAINING ON HOW TO DO THESE PROPERLY).

Also, bear in mind that our bodies are pretty good at adapting and getting lazy. Doing the same program over and over again is a great way to plateau, stop seeing results, get frustrated and quit.

That being said, the most important factor in any workout plan is to stay motivated, so whatever works for you, is the best plan for you. Whatever advice people give you, just make sure it's something that you can see yourself sticking to, and if you try a workout and don't like it/find yourself dreading going to the gym, then find something different that you look forward to doing.
