Design outcomes

Primary

Measure	Time frame
Upper-body strength, measured as 1RM in bench press. Will be assessed pre and post the 5 week intervention. Muscle coordination, measured by extracting muscle synergies from surface electromyography (EMG). Will be assessed pre and post the 5 week intervention.	—

Secondary

Measure	Time frame
Compliance. Will be measured at each training session.	—
