The great weight debate: Researchers find all forms of weightlifting build strength and muscle, details matter less

Researchers found that all forms of resistance training are beneficial for building strength and muscle, with details mattering less than previously thought. The study analyzed data from over 5,000 participants and found that complex prescriptions are sufficient but unnecessary for gains in strength and muscle size.
