Unless otherwise specified, your work sets should generally be the same number of reps/ same hold time as the standard for mastery. You can do these as part of your warmup after mastering them, or you can have a dedicated time for developing these movements further. Do as many sets as you think will be productive - this might be just one, or as many as five.
Foundation 1
MN/PE2>iM: Jefferson curls
Slowly build up over time to performing these with 1x bodyweight.
HBP/PE2>iM, HBP/PE3>iM: Xiapeng forwards and backwards
And finally, a post by Coach about finding the sweet spot for these exercises: "more must always pay dividends".
This topic is to list exercises for which it is beneficial to continue improving in weight/ROM/Reps even after reaching the course's standards for mastery. Let me know if I forgot any and I'll update the first post. Please include a citation in your post. If you can find a citation for an exercise that doesn't currently have one, please post that, too.
