When my legs feel like jelly [1], I know I did a good workout! But here's the thing: leg day [2] doesn't have to take hours at the gym. Even carving out 20 minutes of your day — which is less time than it takes to clean out your inbox — can help you get leaner, stronger legs [3]. And, while you could do a million squats [4] or lunges in that time, following a workout on YouTube is a lot more fun in my opinion. So, get ready to strengthen your calves, quads, hamstrings, and glutes in just 20 minutes — my favourite (quick) workouts are ahead!
