For the seated Russian twist (and one or two other exercises I’ve come across) you are told to use a weight but not given guidance on what weight to use.
For that specific movement, I can easily perform the reps with a 5lb weight, and a 20lb is too much. Should I be continuing on with 5lbs or waiting until 20 is easy? It would be great to have this guidance directly on the app, but I also didn’t find much searching the forum. Thanks!
