Guys, need advice here.

Last two months i was diagnosed with a Degenerative Disk Disease (DDD) which my L4/L5 disk got bulged and the disk between it look a bit drain (blackish in MRI). So i've been stop going to gym for a month or two since doctor advise me to reduce my gym activities and mentioned only to do bench activities (no independent weight activities and of coz no deadlift or squat! ). Since then, im trying to find the right pattern to achieve overall body training but lack of knowledge (my search on google does not help me a lot) put an end to my quest.

Can anyone advice or guide me on the right exercise?
