DVDs are 5,000 yen for two. Please let me know in the comments! Masahiro Sue, a senior with 35 years of training experience, has opened a gym in his hometown of Saitama!! Hayato Aizawa sees machines he's never seen before in this private space!! When you think of Masahiro Sue, you think of his back!! This time, the real battle is back training! Sue, who declares that "you don't need to extend your arms when training your back," skillfully changes the attachments on the same machines to target different areas! Hayato Aizawa, who has "never received assistance with back training," is completely blown away! Will watching the fifth installment of this real battle, where they discover new stimuli, revolutionize your back training?!
