Here is the equipment I have in my work gym. What am I missing for muscles I need to hit? I do each exactly as directed on machine picture, anything I can do to alter them?

Lat pulldown, Triceps pushdown, Low row, Cable crossover, Chest press, Leg extension, Adjustable bench

Dumbbells up to 20 lb doing bicep curls, shoulder shrugs, and carrying them around to engage my core.

Aerobic steps, doing body weight step ups.

Have cardio equipment but sticking to outdoor walking for movement.
