Why do I experience tingling in my arms after a workout?

Tingling in your arms after a workout can be caused by poor circulation, nerve compression, or muscle fatigue. When you exercise, blood flow increases to your muscles, which can put pressure on nerves and cause tingling sensations. It's usually temporary and should improve as your body recovers. If the tingling persists or is accompanied by other symptoms, it's important to consult a healthcare professional.
