I used to train fairly regularly but mostly cardio.

After injury and Covid have sidelined me for a while, I've realised that although I'm now back running regularly, I've let strength training slide.

I used to do a few sit ups, press ups, pull ups and dips but it's a distant memory - is it just a case of repeating the same old exercises or is there another way?

Diet tips would be good too. There are lots of running threads so hoping not to stray into that area too much.

Forgive me if there's already a thread on this that I've missed.
