If the concept of power coaching as soon as conjured younger males thrusting a barbell or coming out pullups, the tides have since turned: Lifting, even lifting heavy, has lastly gained cultural cachet amongst girls of all ages because of consultants who’ve lengthy espoused its advantages for ladies’s bones, metabolism, and extra.
