Eat More. You need to eat more calories than you burn in order to gain weight. Most guys will need at least 3000kcal/day, skinny guys with fast metabolisms will need even more. Start eating at least four meals a day – breakfast, lunch, dinner, post workout. Eat your stomach full on each meal.
Get Stronger. Strength is size. Increase your Squat to 140kg/300lb, increase your Bench Press to 100kg/220lb, and increase your Deadlift to 180kg/400lb. This will increase your overall muscle mass.
Rest. Muscles grow when at rest. Give your arms a break, they’re small muscles. Check StrongLifts 5×5: the routine allows for plenty of rest.
Track Progress. Weigh yourself and measure your arms every 2 weeks. If your arms aren’t getting bigger you’re not training properly or not eating enough food.
Avoid Curls. Increasing your Squat & Deadlift will build your arms faster than biceps curls & triceps extensions. Get stronger and eat more.
