360° Of Exoprecise Forces

The sphere of Exoprecise ® ℗ nanofibers surrounds the upper-body, balancing the forces of acceleration/resistance (yin-yang), improving the performance of your baseball/softball swing. Anchoring at the elbows, attaching securely to the body; when not in use, slide out your arms, wearing around the waist – easy access.

Exoprecise ® ℗ Nanofibers

Three-Dimensional, elastin nanofibers; woven, microstructural layering. Our Exoprecise ® ℗ Nanofiber design produces the stretch of elastin, smoothness of the skin, the flexibility of fasciae, speed of the fast twitch fibers, the strength of muscles/collagen, push and pull forces of the ligaments/tendons, the stability of bones/joints, and balance of the spine.


Ultra-thin, lightweight, unobtrusive, wearing for long periods. Impervious to repetitive motion, reducing friction on the arms, chest, and back; Exoprecise nanofibers, dispersing the heat, eliminating skin irritation.


Synchronously, expanding, contracting, reacting, and morphing to the body’s natural motion.

Ultra-high PSI tensile strength, and stretch-limit; resilient to breaking under tension, accommodating to the stresses, and strain of power-hitting biomechanics. Passing, rigorous testing under extreme conditions.


Durable, returning to the original shape, without permanent alteration.

Sizing Tip

Proper Exoprecise Forces

Wearing for the first time, raise both elbows to the side, checking for proper Exoprecise forces.

Increase the size:

  • Overwhelming resistance.
  • Force pulls the ROM1 Stabilizers up the arm.
  • Bunching of the Exoprecise material, near the Balance Sliders.

Reduce the size:

  • Underwhelming resistance.
  • ROM1 Axis Stabilizer is loose, flapping on the middle of your back.

Unobtrusive, comfortable material, accommodating the full flexion and extension of the arms, anchoring the Exoprecise; throughout your baseball, and softball swing.

  • Adjust the size for a snug fit.
  • Stretch, and slide the arms inside, inserting one arm for isolation exercises.
  • For best performance position on the skin, alternatively, wear around your sleeves.
  • Place directly above the elbows for maximum resistance, optional to place at the mid-bicep, reducing the force.

Gliding the ROM1 Axis Stabilizers along the silky-smooth Exoprecise nanofibres, linking 360 degrees of unbroken force. Balancing the Hit Lasers Bat Speed Trainer, after resizing; slide and align the ROM1 Axis Stabilizers to your hips.

Wearing, on the arms; slide and align, adjusting anterior, and posterior forces:

  • Slide to the inside of the bicep, increasing frontal forces.
  • Slide to the middle/outside of the bicep (recommended setting), balancing the forces.

Complete range of motion for sports

The ROM2 model accommodates, raising both arms above your shoulders, for example, a slam-dunk. During batting practice, proper sizing and fitting of the ROM1 stabilizers, hold the Hit Lasers Bat Speed Trainer in place; for all body shapes/sizes. However, players matching the criteria below, preferring a greater margin for error when sizing; we recommend the ROM2 model for extra hold/support.


  • Youth players with smaller arms.
  • Female athletes, for example, fastpitch softball players; bigger than a B cup, bra-size.
  • Players, using an extremely high two-handed follow through; for example, Prince Fielder.
  • Players, wearing loose and thick sleeves for batting practice.
