  • Bought this for muscle building! It's fine so far, but I'm worried it might break.

It has improved!

"Training tube" is popular as a support product for dieting and muscle training.
Before improvement, "TPE (Thermoplastic Elastomer)" material is used. It has the characteristics of being soft and elastic like rubber, but by changing to "latex" this time, we have increased its strength. It is easy to use because it can withstand high-strength pulling without tearing.

You can choose from 3 different strengths.
◆Soft (SOFT)…Load strength is about 5kg. For those who are new to muscle training and those who want to use it for rehabilitation.
◆Middle (MIDDLE)…The load strength is about 7kg. For those who are accustomed to muscle training.
◆ Hard (HARD)…Load strength is about 9kg. For those who want to do muscle training in earnest.

Customer comments

  • For me, who is a muscle training beginner, it works so well that even though it is soft, my muscles are sore! Because it is a reasonable price of 100 yen, I bought 3 types and enjoy muscle training with my family ♪

  • It looks colorful and cute! I bought this because telework has increased and opportunities to move my body have decreased. It doesn't take up much space when folded, so I put it by my desk and use it in my free time. Before, my shoulders were stiff, but after using this, I feel a little more comfortable.
