I love volume, but what you have isn't a lot of volume. It's a lot of bullshit. Single leg press? Flies? Lunges? Dude, what are you doing?
Squat, deadlift, push stuff away from you, and pull stuff towards you. Don't worry about variations yet. You need to get stronger in these 4 things. If you need to lose weight, then do everything in your power to get stronger in these 4 things while you lose weight.
Don't worry, most people do what you've done. They stuff a bunch of crap in a program, but that's all it is; crap. Cut out anything that isn't making you stronger.
