The posture trainer for significantly improved body awareness. The Posture is unisex with adjustable straps. The Posture S/M/L is ideal for up to men's T-shirt size L. For larger sizes (women's and men's), please order the Posture 2.0 XL/XXL. The posture trainer is an easy-to-use and extremely effective tool. Even with the first use, the strap provides noticeably improved body awareness. The Blackroll Posture can be easily worn under or over clothing, for example, at the workplace in front of the computer or during a workout. The posture trainer is a direct support for good posture. The Blackroll Posture can be perfectly adjusted to the body using a Velcro strap. At the beginning, the Blackroll Posture should only be worn as long as one is actively able to keep correcting their posture. This active straightening and pulling the shoulders back can lead to muscle soreness. Once one is just "hanging" in the Posture, it should be removed to give the muscles a few hours of rest. Often, a tight chest muscle can also hinder the ability to maintain an upright posture. To maximize the effect of the Posture, it is necessary to intensively release the chest muscles two to three times a week. The use of the 8 cm ball, as shown in the video below, is particularly suitable for this purpose.
