Get a gym-style workout in the convenience & comfort of your own home with these expertly engineered, adjustable dumbbells

Working out from home has become very much the norm in recent times, with many of us finding it a much more convenient option than travelling 20 minutes to and from the gym daily. However, not all of us have room to store high-tech machines and equipment in our homes, which can ultimately lead to inferior results.

Dumbbells form an essential part of any effective chest, back and arm workout. Perfect for bicep curls, shoulder/chest press and tricep kickbacks/overhead extensions, they can also be used to work the lats and other large muscle groups in the upper body. However, perhaps the most versatile piece of exercise equipment, they can be incorporated into leg workouts, ab exercises and cardio/HIIT too. This makes them the ideal choice for working out from home. However, there are drawbacks to dumbbells when training, such as, storage space. This is an issue for solid dumbbells as well as standard adjustable ones, which require plates to be stacked. Another annoyance, that many of us are all too familiar with, is changing weights and fiddling with clips on adjustable dumbbell bars between sets. This oftentimes ends up taking longer than the set itself.

The Osalis Health & Fitness Twist Lock Dumbbells have been expertly designed to ensure a gym-style workout in the convenience and comfort of your own home. Indeed, ranging from 2.5kg-24kg or 5kg-40kg, their heavier weight even facilitates effective dumbbell squats, which are a great alternative to using a free weight barbell or smith machine in the gym. Promising the same, if not superior results from your workouts, this innovative exercise equipment offers all the benefits with none of the drawbacks of standard dumbbells. Not only do they take up very little storage space and come complete in a base unit, they also feature a unique weight selection dial that enables the user to quickly and easily adjust the weight in as little as 3 seconds. This actually enables you to change your weight mid-set if you have over/underestimated your strength, which is impossible with your typical dumbbell. Allowing you to gradually increase your weight and employ progressive overload, you will continue to notice increased muscle growth, strength, and definition.

Ergonomically designed, the Osalis Health & Fitness Twist Lock Dumbbells are incredibly easy to use. Featuring a weight selection dial at either side, it is simply a matter of placing the dumbbell back in the base unit, gently pressing down and rotating left to increase the weight or rotating right to reduce the weight. Because the weight can only be adjusted when it in the base unit, the plates are securely locked in place and won’t slip out of place as you exercise. In addition, there is a reset button for when you finish your workout. Featuring a water-resistant rubber grip on the handle, these expertly engineered dumbbells ensure optimum control and form, thereby reducing the risk of suffering a sports injury. It also eliminates the need to wear gloves and makes it the perfect alternative to purely metal dumbbell handles, that have been known to start to splinter as they age.

Complete with a solid inner core made from static silicon steel and with a high strength nylon outer casing, the Osalis Health & Fitness Twist Lock Dumbbells are not only durable and built to last, they ensure little noise when placed down between sets and will not do damage to any of the floors in your home. The base unit is also manufactured from the same high strength nylon meaning it supports the weights with ease and will not break easily. Featuring embossed numeric keyboards and bold red and black colours, these dumbbells are not only highly effective and convenient, they look superb and will not compromise the décor in your home!

The Osalis Health & Fitness adjustable dumbbells are available to buy individually or in pairs, depending upon your requirements. You decide how to incorporate into your training session.
