Would appreciate help with my routine (15M)

I’m looking to completely overhaul my physical appearance. My thought process is that- if I’m gonna hold myself to a routine- it should be a damn good one.

{15, male, around 5’8”, 205 pounds at last measurement}

My current routine is:

Chest+Triceps: Knee Pushups; 2 sets of 50 Decline knee pushups; 2 sets of 50 Diamond knee pushups; 2 sets of 50

Legs: Lunges (with weights); 3 sets of 25 Squats (with weights); 3 sets of 20 Side lunges (with weights); 3 sets of 20

Back+Biceps: Bent Over Backpack Rows; 3 sets of 20 Super mans; 2 sets of 30 Towel Back Extensions; 2 sets of 50 Backpack bicep curls; 2 sets of 20

Abs: Crunches; 2 sets of 50 Russian twists (with weight); 2 sets of 50 Planks; 2 sets 1:00

Cardio every day

If I didn’t clarify anything please ask- thanks for reading
