What are the best workout routines?
I want to build muscle and improve my overall fitness.
In that case, you may want to consider a combination of strength training and cardio exercises. A good place to start may be a full-body strength training routine like the '5x5' program, which focuses on compound exercises like squats, deadlifts, and bench presses. To complement this, you could also incorporate some high-intensity interval training (HIIT) for your cardio workouts.
