Are there any submissions or moves that you're afraid to use for fear of injuring your partner? For some reason, I'm terrified of using the straight armlock. It seems like a move that a lot of guys resist and I feel like I may accidentally pop an elbow. I don't really know my own strength when it comes to my arms. Every other sub either comes from your core or your hips. I feel like it's easier to apply slow controlled pressure that way. But I feel like I might accidentally go 0-100 on a straight arm. I'm also afraid of doing any kind of jumping guard passes. I'm heavy and I'm afraid of hurting someone.
