Weight training is the most common type of strength training, utilising the force of gravity in the form of weights to increase your strength, stamina and overall health. The most common types of weights used for home workouts are barbells, dumbbells and kettlebells, although you can substitute these with household items such as filled water bottles or books in a rucksack if you do not own these items. Any exercise performed with weights should be executed with the correct form and posture to ensure that you are performing the movements with the appropriate muscle groups and that you are not putting yourself as risk of injury.
