First, I'll put the disclaimer in that I'm not a personal trainer...just someone who's been into lifting/exercising/nutrition for many years.
Lifting for women really shouldn't be any different than it is for men as far as the exercises you do. It's more about how "hard" you lift and how you feed your body. DW actually is more hardcore than I am. I weigh and measure a lot of my food, but she literally weighs how much salad mix goes into her lunch or dinner and counts every almond she eats. She also is stronger than I am in her lower body, she can squat and press things that would make my ligaments snap. She and I do a lot of the same exact lifting exercises...and frankly a lot of the variation between us is more about comfort level than differences in men vs women...i.e. some things she does are painful for my joints so I do alternatives.
I like that bench, actually. I like that it can incline and decline. As for a lifting program, for sake of discussion, I'll just give a sample 5 day routine. If you have less time, you can alter it to suit your needs. And this would be assuming you have nothing but dumbbells (if you can get an Olympic bar and weights too, great). Do as much weight as you want/are comfortable with. So...some ideas...you can
YouTube or Google the exercises if you don't know what they are. Maybe do 3 sets of 10 of each exercise (or as close to 10 reps as you can)...don't do all of the exercises, pick 2 or 3 each week and rotate. There are many more than these, just some examples off the top of my head.
Monday = back. Bent over rows, reverse fly, trap raises (upright rows...these work shoulders too, but also the back), trunk twists (works your abs, but helps lower back), if you can find somewhere to do pull ups, hyperextensions, supermans
Tuesday = arms. Standing curls, hammer curls, spider curls, preacher curls, skull crushers (don't worry, not as bad as it sounds), triceps dips, overhead triceps press
Wednesday = shoulders. Front raises, lateral raises, incline lateral raises, Arnold presses, shoulder shrugs, upright rows, incline front raises
Thursday = chest. Dumbell press, incline press, decline press, fly, incline fly, decline fly
Friday = legs/abs. Squats, lunges, walking lunges, reverse lunges, calf raises, stiff leg deadlifts, crunches, incline sit ups, v ups, trunk twists, leg raises...hold your feet 6" off the floor while lying on your back, (there are SO many ab exercises, just do a quick Google search)
