For reference 159 pounds would be where you start to cross into an 'unhealthy' BMI. However, while BMI is a good gauge for normal/sedintary people, it isn't a great measure if you're quite muscular. So I would try to stay under 160 unless you've been building miserable consistently for 1-2 years. And even then, if you are trying to optimize health, no need to go much over, even 160 being swole. However if your primary goal is not health but strength, you'll need to be 'obese'. Which is still healthier than being thin and out of shape, but not 'optimal' for long term health. The reason I say this is, everyone has an opinion on what's best, but it really depends on what you're trying to optimize for.
