I am a bit of overweight guy and I don’t know anything about lifting and fitness. I can’t go for strength due to very weak joints. (no loaded squats) I would like to go for body building or hypertrophy training. Some pointers, tutorials and links to resources are welcome.
As equipment goes I only have resistance bands, a bicycle and an outdoor gym.
Also how important is a diet in keeping myself fit?
I’d recommend ‘convict conditioning’ by Paul Wade. Free pdf / epub is easy enough to find with a quick search. The book does a better job of describing itself than i can, but basically it details 6 “power moves” (push up, squat, etc) and 10 steps within each move-set, 1 being the easiest/introductory exercise and 10 being the ‘mastery’ of the movement. I.e for push ups- step 1 is wall push ups and step 10 is one armed push ups.
Im actually gonna try to double down on this recommendation after re-reading that you also have joint issues. Step 1 of each of the ‘big 6’ is picked with this issue in mind and tend to describe them as good “therapy” excercises for people recovering from injury/surgery/illness/etc.
I’m not saying this guarantees you’ll be able to work up to one armed push ups (im still mountains away from that feat myself) but if regaining joint strength/durability is one of your main areas of focus, id very strongly recommend at least skimming through the 1st step or 2 in each of the big 6.
It’s also got a chapter on self coaching, which ive found very useful to revisit every now and then
