How To Bulk Like A Pro (Using Science)

Summary

Key Points

• —While old-school "dirty bulks" build muscle, they lead to excessive fat gain, causing many to avoid bulking altogether and opt for slower "main gaining." 0:48
• —Bulking, defined as eating in a caloric surplus, is the most effective method for building significant muscle mass compared to "main gaining" (eating at maintenance calories) or "recomping" (body recomposition). 1:10
• —The recommended rate of weight gain for a lean bulk is 1-2% of body weight per month for beginners and 0.5-1% for intermediate to advanced lifters. 4:16
• —A proper lean bulk involves a controlled caloric surplus of 5-10% above maintenance to provide the body with resources for muscle growth without excessive fat storage. 5:19
• —To determine caloric needs, one can estimate maintenance calories by multiplying body weight in pounds by 14-18, or more accurately use an app like Macro Factor to track intake and weight over time. 5:56
• —Adequate protein intake (0.7-1 gram per pound of body weight) is crucial for muscle protein synthesis during a bulk. 6:39
• —Dietary fat intake should ideally be 20-30% of total calories, as too little can lower testosterone and too much can lead to increased fat storage. 6:51
• —Training intensity and volume must be maintained or increased during a bulk; neglecting training will lead to more fat gain than muscle gain. 9:21
• —Cardiovascular exercise is beneficial during a bulk for overall health, improved work capacity, and better tolerance for training volume, especially for those with sedentary jobs. 11:01
• —Key supplements like creatine, protein powder, fish oil, magnesium, and vitamin D can support muscle gain and overall health during a bulk. 11:34
