Bulk will come with time, but what I saw from your videos is that you're not using your current mass properly to generate pace - and it's all footwork.
You're fast, but you're not stepping INTO the shot - that change alone will increase weight of your shots. I'd focus on that to begin with.
As far as working out, focus on explosiveness, flexibility, legs and core. ladder work, jump rope, squats, planks, jumping jacks, burpees. stay away from heavy weights.
