If you want to develop your muscles and improve your strength, you might want to consider using 5kg dumbbells instead of dumbbells that are designed for bigger individuals. The main reason why it's more effective to use dumbbells is because they can provide resistance that is comparable to that which you're exerting in your workouts. With the right set of weights, you'll be able to do more reps and give your muscles time to recover faster after your workout.
When you use larger weight sets for your workouts, you'll have a lot more control over what you're doing and therefore you'll be able to train harder without feeling like you're under too much stress or pressure. This is why many people who are interested in developing their body will try using dumbbells as opposed to machines.
One thing you'll need to keep in mind is that dumbbells can be very expensive, so if you want to get them for cheap, you might have to resort to the use of free weights. If you're used to using machines and don't want to spend a lot on gym memberships, you may want to consider using free weights for your workout. In fact, using free weights is something you should really consider, as they aren't expensive and don't require you to purchase a gym membership, although they do require you to take the time to learn how to use them properly.
In addition, free weights usually come with a good set of weights that you can use to workout different parts of your body at the same time. If you use free weights, you'll be able to exercise the whole body at one time, which is something you don't normally get with machines.
You might also find that using heavy weights for your workouts is beneficial because they give you a lot more stability while lifting, which will help you avoid injuries and increase your performance. This is especially true if you're trying to work out heavy weights in a single set. When you're lifting these weights, you won't be lifting the same weight twice in the same place, which means that you'll be preventing yourself from lifting the wrong weight.
With the large dumbbells you're going to be able to get, you'll find that the sets that you need to complete will be smaller as detailed at https://fitnesshub.co.uk/strength-training/dumbbells-and-hand-weights/5kg-dumbbells/. However, you won't have to worry about finding a lot of weights, as there will be a large number of dumbbells available so you'll be able to complete multiple sets in a short amount of time.
