Rock Gym from Tristar Products is a piece of exercise equipment that promotes itself as an 8-in-1 body trainer that will give you rock hard abs with just a few minutes use each day. Rock Gym touts a dynamic neck and back support system that makes sit-ups easier yet more effective and can be used by people of all fitness levels to chisel your entire midsection.

What’s So Great About Rock Gym?

Rock Gym states it has been scientifically designed to offer both more comfort and greater efficiency. They state Rock Gym uses dynamic support with 9 soft cushions that massage your back and a high-tension spring system that provides resistance on the way up as well as on the way down. This way, they claim you can exercise with minimal back strain while increasing muscle activity in in and around your abdominals aka “abs”. 

To “rock” your way to tight, sexy abs, they instruct you to simply lie back and begin working out by sitting up; they state you will be able to do hundreds of reps easily because you are off the floor and are gently supported from head to toe. Rock Gym also comes with push up handles, a leg extender, and 2 resistant pull cords which they claim you can use to sculpt your arms, chest and back; they add Rock Gym’s bench is also adjustable for more upper and lower body workouts.

Bottom Line: Will Rock Gym Help Me Rock My Way To a Hot Bod?

If you are interested in getting a fitter body, we applaud you. A proper diet and exercise is truly the best way to both look and feel better. We couldn’t find any specific reviews of Rock Gym, but we’ll go over some of the pros and cons that we do know:


  • Rock Gym may make it more convenient for you to exercise in the comfort of your own home.
  • It appears to be relatively compact with not a lot of moving parts that can go wrong.


  • Doesn’t appear to have too many resistance levels.
  • Doesn’t give you a cardio workout, which is important in weight loss/ab training.
  • You will have to assemble it yourself.
  • The warranty only lasts 60 days.
  • Shipping back can be expensive.

You should also note Rock Gym expressly states: “The Rock Gym does NOT cause weight loss and does NOT give you well-defined abs.” This is for legal protection but does point out a few things.

First, in order to lose weight, you generally have to eat less. The product does come with an eating guide, but you can find many of these online, including this one from Bodyism. Because the body stores fat all over and you can’t target weight loss in one area, your rock hard abs could still be covered by a layer of flab.

Second, you don’t necessarily need a machine like Rock Gym to get sexy abs. There are many different devices and workouts to choose from. About: Health rated their top 10 pieces of ab-defining equipment: number one was a kettle bell and number 2 an ab wheel

Currently (June 2015) Tristar Products has no rating from the Better Business Bureau, who says it is in the process of a review. Brightreviews consumers have commented on a number of their products including Power Pressure Cooker XL (2.5 stars) and Slim Jeggings (1.5 stars) often complaining about lousy customer service and crappy products

If You Are Interested in Getting Rock Hard Abs

If you’d like to look like you have six-pack abs (men) or a tight tummy (women) we recommend a sensible diet and exercise plan, doing as much as you can without expensive equipment first. Generally speaking, the majority of people that start fitness programs don’t follow through, ending up spending a lot of money on equipment that collects dust.

Therefore, we say check out Abs: From Flab to Fab in 4 Weeks from WebMD and go from there.
