The bony knob below my right elbow aches while doing skullcrushers few days back, it happened again yesterday when performing the same exercise. Thought I might have bump into something hard initially and massaging is not helping either, today then I realized it's a elbow injury.

I know it takes time to heal, don't want to sit around idle as I exercise 5 days a week, already a habit for me. What sort of upper body exercises can I perform without further straining my right elbow?

Aiksss.....Skullcrusher is my favourite exercise and I only workout from home. No cable machine, will find other alternative or lighten the load. Thanks for your information, difinitely do a switch after signup for gym.
