RT @xst2020: @Svwang1 It can be extended to be more fun. Push-ups can evolve into narrow-grip, wide-grip, side-to-side shifts, and clapping exercises; pull-ups can evolve into butterfly exercises, chest touch exercises, double arm exercises, and ring double arm exercises. Such exercises abandon the single-threaded impact and emphasize more control. Breaking through plateaus will also be more enjoyable, feeling like all the muscles in your body are engaged, not just a single area.
