Kettlebell sets in this category contain weights of 18 and 26 pounds or 8 and 12 kilograms.
Women who are new to kettlebell training and lifting in general should start with an 18 pound or 8 kilogram kettlebell for explosive movements like kettlebell swings. This weight is ideal for a woman who is just beginning weight training whether it be in the gym or at home.
Remember, you want a kettlebell you can grow with, even if this seems like a lot of weight at first, you will fairly quickly be able to increase your reps through regular use and workouts. So, the 26 pound kettlebell is perfect for you to grow in to after a couple months of use. You will always be able to use the 18 pound kettlebells for isolation movements like presses and get ups, which do not rely on full body strength but focus on specific muscles.
For anyone who is going to be using kettlebells, a kettlebell set is great purchase. First because it will allow you to grow with your kettlebells and give you some variety as your strength increases for certain movements, but also because of the heavy discounts which are applied to sets versus individual purchases. It is hard to make recommendations without knowing you specifically, but this is where most would start.
