@Mr Carlo Peroni, welcome to the forum. The method you have outlined is certainly one way to do it. Alternately, you could start your swings with the 32 and when you notice your technique drop, switch to the 24 to finish out. You can also do a more planned approach and integrate the heavier weight one set at a time over a few weeks or months as needed until you are swinging the 32 for all 100 swings. If you search around the forum you will find a lot of methods for making the transition. The best advice I, and many more qualified members will tell is, listen to your body and only increase when you feel you are ready. Enjoy the journey, and be patient, it is worth it.
