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?
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
