Best practices for safe weight lifting include proper form, gradual progression in resistance, and appropriate warm-up and cool-down routines. Maintaining a neutral spine and using controlled movements help prevent injuries. It's also crucial to breathe properly throughout lifts, exhaling during exertion and inhaling during lowering phases. Setting realistic goals and allowing adequate rest between workouts aids in recovery and muscle growth. Lastly, consider seeking guidance from a certified trainer, especially for beginners, to ensure correct techniques and personalized training plans.
