Educational guidance, not an individual training prescription. Start with a manageable load, work within a comfortable range, and stop if a movement causes pain. Ask a qualified coach for help with an unfamiliar setup. Practice the technique before increasing load. Repetitions and working weight depend on your goals, experience, and individual needs.
