Although the item looks good enough , it doesn't appear to be calibrated as per sports standards. Compressing is too hard. It'd be better if its sports compliamt

Hahaha! I am a senior citizen 75+. I used to use Bullworker during my younger days as it was a new item in Exercising called as Isometric Muscle trainer. I found it quite good. For the new year 2026 I decided to start exercising again and believe me this is the best all-round trainer at a very economical price. I found in Amazon an Equivalent product and Ordered it. However as a Follow-up I wanted some details about the product. Now Amazon has no Idea about how to contact the Seller and the people at the Address mentioned in the Product say that they don't sell their products through Amazon. Add to all these you can't Contact Amazon quite easily and their Virtual Assistant do not understand our problem and keep repeating the same message. Now what is the Solution?

A complete workout in less than 30 mins. Simple and very effective. Keeps your body slim and trim. Those of you who have used it in their younger years will definitely vouch for it.
