Self-Massage Your Muscles Say goodbye to muscle pain with a Core Balance High-Density 2-In-1 Foam Roller. The roller features a main roller and an inner roller which are different thicknesses to target a wider range of muscle groups. Made from EPP foam, they’re perfect for digging deep into those sore spots. /// Main Foam Roller The main roller measures 33cm long (13”) and has a diameter of 15cm (6”). It’s a comfortable height to ease your body onto, so you can roll out your muscles with greater precision and control. Its length makes it ideal for rolling larger muscles, such as your glutes, lats, and thighs. Inner Foam Roller The inner roller has a length of 33cm (13”) and a diameter of 6cm (2.3”). Its size allows you to hold it with both hands and comfortable roll areas the main roller is too large to reach, such as your neck and arms. It’s also great for massaging your calves and the top of your thighs. Massage On The Go The main roller has a hole running through the middle which the inner roller seamlessly slides into. This allows you to easily store and carry them together. Lightweight and compact, they’re perfect for popping in your gym bag, so you can self-massage your muscles wherever you go. High-Density EPP Foam The rollers have a high-density EPP (Expanded Polypropylene) foam construction and are a top choice for anyone who works out regularly and pushes their muscles to the max. They’re at the top end of the firmness scale to apply greater pressure and dig deeper into your muscles. Smooth Surface Both the main and inner roller have a smooth surface which helps to provide even pressure across their entire length. Although both rollers are strong and firm, they’re less painful to use than a textured roller which has bumps and ridges to deliver a more intense muscle massage. Ideal for Experienced Users Because the rollers are made from high-density foam, you may find the pressure too intense if you’re not used to rolling. If you’re used to rolling and have a higher pain threshold, you’ll find the rollers dig deeper into those sore sports and help your muscles recover at a faster rate. Benefits of Rolling Regular exercise can cause the fascia tissue that surrounds your muscles to tighten up and knot which can cause soreness and tension. Rolling out these sore spots helps to increase blood flow to the target area which helps to loosen knots and soothe aches, pain, and tension.
