How many thrusters should I do?

I'm curious, could you please elaborate on the question 'How many thrusters should I do?' Are you referring to fitness exercises or perhaps something related to rocketry? If it's about fitness, then the number of thrusters you should do depends on your fitness level, goals, and whether you're following a specific workout plan. It's important to start slow and gradually increase the intensity to avoid injury. Alternatively, if you're asking about thrusters in the context of space travel or engineering, then the answer would depend on the specific requirements of the mission or project. In any case, more context would be helpful to provide an accurate answer.
