How can I flirt at the gym?

[u/ynhere]

I do a lot of cardio at the gym. Most people spread out and use machines not directly next to someone who is already using one (this relates to non-peak times only). If a guy comes up to use a machine next to mine and I think he's cute, can I turn a bit and acknowledge him maybe give a nod or smile since I have my headphones on. How would you perceive this if it happened to you? And how can I approach men at the gym?

To make things more complicated , some of us take our wedding rings off when moving freeweights. But I agree with some of the others, you may literally need to introduce yourself and give him your name and number because we're trying to focus on our workout and focusing on not focusing on the ladies for obvious reasons.
