Building strength and muscle after anorexia

Hi guys and girls,
I’m new to the forum however have always been interested in fitness and have wanted to pursue bodybuilding but never got round to it. I know there are loads of experienced people on these forums who might be able to offer some advice and would appreciate any tips I could get...

I unintentionally lost a lot of weight by doing way too much cardio and not eating enough to fuel my workouts... by the time it all happened It was too late and I was left in a very vulnerable and severe state where I had to quickly recover and follow a meal plan to bring my health back up. Now I’m at a healthy weight however it seems like my upper body especially is extremely weak due to the loss of muscle mass that occurred along with weight loss.

I am left in a bad position since i’m now too weak to lift dumbells and have resorted to bodyweight exercises but it seems like it is not making a difference. I would ideally like to gain some more mass particuarly on my upper body as it seems like my lower body still has a decent level of muscularity and strength.
