So I have a 30-40 lb dumb bells, 5-45 plates no barbell, and some bands, what do I do to get ripped.
If the 45 plates have slits in them you can use them to do quite a few things. Ideally do whatever you can to get a squat rack that you can use for benching and squats, but what you have now you can use for alot of things.
Legs- you can do lunges, you can grab the sides and do lunges, or hold them up and do lunges, you can hold the plates and do front squats with them(goblet squats)
Chest- you can lay flat and press the plates, or hold a plate together with your hands(like you are praying while laying flat and push it up for an intense middle chest workout) if you lay the plate on your chest and press up, you will really feel it on your upper pectoral muscles. Combo that with pushups.
Back- you can do dumbbell rows, bend over a chair and arch your back, have a 45° bend in your elbow, and slowly pull the dumbbell parallel to your side, be sure to engage your lats and don't yank the weight.
Arms, you can do overhead tricep extensions with the plate, and overhead extensions with the dumbbell. You can also do rear extensions with the dumbbell as well(same position as the row but instead up pulling it parallel, you extend your arm back to have your arm parallel to your side) the weight might be heavy, if that's the case try and use both arms and do the overhead extensions. If you have steps, or a sturdy chair, you can do dips, and you can put the plate in your lap to make it a little more intense.
For biceps you can do all kinds of curls with the dumbbell, you can definitely YouTube that one, there's a million and 1 different ways to curl a dumbbell, just start off with the traditional way of doing it, and you can evolve from there!
Shoulders- there are many parts to your shoulder, and you really want to be delicate with them until they are strong because a shoulder injury is not something to take lightly. Try and just do shoulder presses with the plates and dumbbells, if you get some lighter weights and can do rear extensions and side extensions. You can also do shrugs with the 45 pound plates. Just grab through the holes in the plates, have them at your sides while standing up, and slowly try and lift the weight up.
Abdominals, you can do planks, crunches, leg lifts, hello dolly's, tons of ab workouts. You can YouTube tons of those as well.
Cardio is always good, if you are trying to be lean and shredded, definitely just do some running 3 times a week, more or less, whatever you feel like doing.
I apologize for being all over the place, but you have tons of capabilities with what you have. I would definitely try and get a barbell for your plates asap, and a rack so you can do squats and bench. Feel free to PM me if you have any questions man, but YouTube is your friend, and there is alot of information on the internet.
Don't go through the motions, engage your muscles, and really feel it. You'll feel the desire to feel a pump, and really fall in love with the act of working out, and not just the results. Good music really helps too.
