Last Christmas I put together a 3 part exercise routine for over the holiday period. I’ve added a 4th section, some side-lying work. Each section is only about 10 minutes, so you could do 1 routine a day or go through all 4 in one go (and then feel smug and virtuous…)
For Part 1 you simply need a mat or a space on a rug or carpet.
For Part 2 you need that same mat or carpet space.
For the side lying work you still only need that small space.
For the final part you need a chair or something similar to lean on, and book or block or something similar about 5-10cms high.
