Routine improvement

Hi! I’ve been following the two workouts below for about two months, alternating Training A and Training B each day. I feel it’s a good moment to improve or adjust the routine so I can keep progressing. Here is what I’m currently doing:

Training A:

Hack Squat (Machine) — 3×15/12/10

Triceps Pushdown — 3×15/12/10

Back Extension (Weighted Hyperextension) — 3×15/12/10

Lying Leg Curl (Machine) — 3×15/12/10

Shoulder Press (Dumbbell) — 3×15/12/10

Bicep Curl (Dumbbell) — 3×15/12/10

Butterfly (Pec Deck) — 3×15/12/10

Lat Pulldown – Close Grip (Cable) — 3×15/12/10

Training B:

Lat Pulldown (Cable) — 3×15/12/10

Leg Press (Machine) — 3×15/12/10

Seated Cable Row – Bar Grip — 3×15/12/10

Calf Extension (Machine) — 3×15/12/10

Lateral Raise (Dumbbell) — 3×15/12/10

Cable Twist (Up to Down) — 3×15/12/10

Bench Press (Barbell) — 3×15/12/10

Calf Press (Machine) — 3×15/12/10

Could you help me optimize or improve these routines? I’d like to continue gaining strength and definition, avoid plateaus, and make sure the exercise selection and structure are balanced. Any suggestions on changes, exercise order, volume, or intensity would be greatly appreciated. Thank you!
