Is it possible for someone very overweight (35+ BMI) to pursue a useful bodyweight strength routine? I'm thinking in terms of someone who has trouble doing barbell weighted exercises due to chronic injuries, but would still benefit from some form of strength training. Provided weight loss and cardio work continues, do you think someone this size could get benefits from this routine? Of course, everything would have to be heavily scaled.
I know someone who is interested in moving to bodyweight work as they continue to reinjure themselves doing barbell work, and I would like to help put together a routine or some progressions for them. However, if it's going to be a waste of time, or progress will be so slow as to be utterly frustrating, I'd rather look at pursuing something else.
