What's the best approach to calculating my surplus for a lean bulk?
I'm currently sitting at 150 lbs and lifting 5 days a week. I want to lean bulk without packing on too much fat. What's a good starting point for my calorie surplus? I've read anywhere from 250-500 kcal, but how do I know if I'm gaining too fast or slow? Should I adjust based on my monthly weight gain? I'm looking for some practical tips to fine-tune this process
