"Strong Is What Happens When You Run Out Of Weak."
With slight modifications you can make this workout much easier or much, much more difficult. There is no fitness level on the planet that can’t scale any strength routine to be “hard enough”. it’s all about dialing in on clean form and then lifting enough to challenge yourself. If you want to make the workout easier, use a lower step, lighter weights, and slower movements. If you want to make it harder, lift heavier, use a taller step, squeeze your muscles antagonistically and use a deeper range of motion. Whatever fitness level you’re at, make sure that you’re challenging yourself.
