Hey, thank you for the reply. I don't really do much core so I can't help you with that.
But I can definitely help you out with back and chest. If you want to do chest but you have no equipment,
then press-ups are your best friend.
4-5 sets, all to failure. Rest before getting up, you may not be able to get up otherwise, lol. This will also give you awesome triceps.
I have a bench press at home so I just do bench-press, incline and flies to do my chest. If you get a bench press then I recommend those exercises.
For back, I highly recommend you get a barbell with some weights and perform these exercises. Dead lifts, Vertical Barbell Row, Barbell Shrugs, Bent-Over Barbell Row, Dumbbell Bent Over Row, with knee on bench. Check on YouTube to see how to perform them properly.
The key is to control the weight, and squeeze the muscle. Do not make the rookie mistake of putting a lot of weight on and throwing it around with bad form, lol.
Doing these exercises will pretty much target your entire back and not leave anything out. Good luck
