The cornerstone of any strength training regime, Reebok Dumbbells are a versatile and effective tool to enhance overall strength and muscular endurance. Engineered with a cast iron core and vinyl outer, the dumbbells are built to last rep after rep. With weights ranging from 1 - 5 kg, Reebok Dumbbells lay the foundation to build upper and lower body strength. Studio dumbbells are usually sold in pairs and are a perfectly good home dumbbell solution if you are looking for very low weight denominations. Studio weights typically range from 0.5kg – 10kg and for commercial purposes can normally be purchased in sets of between 40-50 pairs. Increase the weight by 2.5 pounds (1.1 kg) until you get to a weight that is difficult to use for the exercise. Then, go down one increment. This will be the best weight for you to start at.
