Yes. Resistance training is at the heart of FIT ID as we need to put stress and strain on our muscles in order to get stronger. Light weights and resistance bands are used in some workouts, the idea is to increase the weight or resistance gradually as we get stronger. Some of the other workouts also involve a gym box, this can be substituted with a step, chair or sofa. Resistance bands are used in warm up/activation and some core workouts so it's advisable to invest in some bands, they are relatively cheap.
From the outset we do a range of bodyweight exercises, ensuring form and technique are explained. We then progressively add weights to the workouts which in turn will overload the muscles, making them work harder and become stronger. You decide when you are ready to add/increase the weight, ensuring to take note to track your progress. If you don’t have access to weights, improvise - you could substitute at 5kg kettlebell with a 5litre bottle of water!
