Which do you think is more effective for leg muscle growth: Squatting a heavy weight with two legs or one? I prefer doing Single-Leg Stepups, like here on the Smith Machine with 65kg x 12, so I can focus on activating the entire musculature of the working leg without the lower back burning out with the much higher loads typically used in a standard Barbell Squat. This version also has a much better carryover to athletic power movements in sports ️?️⚽ Try it - you'll feel an almighty ? in your ? #LegDay
