A good set of dumbbells should be the foundation of any home gym. Dumbbells are extremely versatile and can be used for a huge range of exercises that work both your upper and lower body. However, not all dumbbells are the same and it can be difficult to find a set that meets your needs (without breaking the bank).

Our guide to buying dumbbells sheds some light on the main types of dumbbell available.

Thick bar grips are cylindrical pieces of silicone (or similar material) that fit around barbell and dumbbell bars and other fitness equipment to increase the thickness of the area gripped. This essentially turns a regular barbell or dumbbell into a thick one.

Using a thick bar grip will stimulate greater muscle activation in certain body parts. In particular, greater muscle activation is likely to occur in the hands and forearms, as well as in the upper arms and possibly even the whole upper body.

As a result, thick grips can help to develop bigger, stronger forearms and increase your grip strength.
