Our most popular tool for good reason. Imagine stopping a Tension Headache in 15 minutes without taking medication. The Twin Block Pro provides a perfect sub-occipital release without the aid of a therapist. Don't wait to start a new chapter in your life! This Manual Massage Tool does much more than improve neck mobility and muscle health. Use the included Twin Block without the base to powerfully target muscle tension from the base the neck, traps and mid shoulder region. No need to stop there, this really is a whole body tool, work your Glutes, mid back, Quads, IT Band and Calves (Gastroc/Soleus). For decades therapists have been taping tennis balls together and/or placing them in socks as therapy devices. Now we have Massage Blocks® manual massage tools. The Twin Block is a meticulously designed well-engineered tool made from premium material in the USA.. Our trigger point tools are strikingly more powerful and infinitely more useful than other manual massage tools on the market. Perhaps the greatest benefit to users is the ability to target muscle tension within minutes of noticing the first signs of a headache or moments after a muscle strain. We are continually reminded how important it is to target muscle tension as early as possible, before it has become entrenched. This kit includes a Twin Block and Large Base from Massage Blocks®.
