@trainwithpb: 💪 Want bigger arms? Focus on your triceps — they make up about ⅔ of your upper arm mass. Most people overtrain biceps because they’re visible, but it’s the triceps that give your arms real size and shape. 👉 Tip: Prioritize heavy compound movements like close-grip bench or dips early in your workout, then finish with isolated extensions for that burn. 🎯 Don’t just train what looks good in the mirror — build the muscle that actually makes a difference. #TricepsOverBiceps #BiggerArms #ArmDayTips #MuscleBuilding #TricepWorkout #FitnessEducation #TrainWithPB #SmartTraining
