Are you working around an injury? Don’t have a piece of equipment? Have to adjust the order of exercises or break up a superset? Don’t worry about it! Our recommendation will always be to follow the program as written as closely as possible. With that said, we know there will always need to be substitutions made whether you are working around an injury, have limited equipment/space, have to work around other lifters, or for any other reason.
While following the program to a T is ideal, we would rather have you do a modified version than skip something altogether. Most movements have suggested substitutions. Once you start the workout, there is a link under each exercise:' Substitute exercise'. When you click on this link, there will be exercises that closely mimic the prescribed movement.
For any exercise that doesn't have a substitute for the prescribed movement, a bit of flexibility and creativity goes a long way. The closer you can mimic the movement, the better.
Ask yourself what body parts or movement patterns the exercise targets, if the exercise is a multi-joint compound movement or isolation, machine or free weight, unilateral or not, which plane is it (e.g. while both target your back, a row is a horizontal pull while a lat pull down is vertical), etc. Do your best to match as many criteria as possible, but adjust as needed.
