Started my bulk in September after a summer cut. Goals were to put on size without getting too fat since winter and hoodie season's coming. Started at 160lbs, yesterday's evening weigh-in was 175lbs.
I'm on a 3000-3500 calories a day diet. Breakfast is toast, eggs, and a shake. Midmorning snack is banana with peanut butter. Lunch is chicken, whole grain rice, and veggies. Afternoon snack is a handful of nuts (almonds are the best). Post workout I take another shake. Dinner is usually a repeat of lunch.
Gyms are open so been doing PPL 6 days a week and resting Sundays. Starting to see some good improvement on my lifts (especially deadlifts going from 1.5x bodyweight to 1.75x).
You don't need fancy, expensive supplements to gain, just lots of food (and lots of patience)!
Good progress man! Bulking in winter is the way to go. Do you find the 3000-3500 calories enough, or do you somedays feel that you need more? Also, how are you finding the PPL, any particular program you're following?
