Myontec MShirt Plus is capturing astonishing 16 channel EMG (forearm extensors and flexors,  Biceps, Tripeps, Deltoid, Trapezius, Pectoralis and Latissimus muscles on left and right side) but also bending and overhead positions with 3 IMU sensors.
 
MShirt Plus requires three MCell to cover all 16 muscle groups (sold separately), and it works with Myontec Muscle Monitor and ErgoLink software (sold separately).
