You can google on bodybuilding for mesomorphs. There's a pile of articles online about somatype-specific training.
Honestly, most of this would be contingent to your goals, your personal recovery ability, your training intensity, your caloric intake, your sleep patterns, your stress levels, the number of years you've trained, and so on.
E.g., I've been training for 33 years. My recovery ability is exceptional. I'm a classic mesomorph who has been studied, but, I have both myostatin inhibition genes (the super big guys sometimes lack the one myostatin inhib gene, and in just few, they lack both), even though I weighed 175 at 5'5" in high school. I can do a large volume of work without over-training, but, at my advanced level, I get tired of training, if I don't have a goal like competing, so I'm rarely in the gym more than 90 minutes.
As I've gotten older, I've learned to train smarter, and recover better, and stay injury free longer. I can easily take my weight to 230, when I eat real well. I've had folks tell me I could go to 250, but, whew...that's pushing the envelope, even for someone with my ability. I hold 205 to 220 without doing anything special, however.
The key is to train enough to stimulate yourself without over-training, and yet enough to promote ongoing gains. Gains, for the most part, in a mesomorph are about calories, and recovery.
If you want to get lean, study up on HIIT. It could serve you well. It does most folks.
For size, you need time under load.
Like I said, it depends upon your goals, and a variety of other factors, mentioned above.
Here's a 16 year old Russian kid who almost certainly lacks one of the myostatin inhibition genes (he's now 20). He's an example of a super-meso somatype. There's another kid who lacks both. You can google on "Super Baby" if you have an interest. The kid below is already a pro bodybuilder at 20. My point being that no matter what he did, he'd still be a super-meso. Notice that he doesn't have a "juiced" look. He's just darn big for a sixteen year old.
