The grips are certified for 180kg (400lb) per handle (or 360kg/800lb if both are used together). Also, you can take a look at our unofficial resistance test that we did with a minivan, which weighed over 1.8 tons (4 grips) - Angles90 Resistance Test

Building grip strength is extremely important. With the help of Angles90 you can definitely increase your grip strength because you have to control the freely-moveable grip - and you can change between grip options. The FOREARM grip option also puts the main focus on your grip strength by putting the ring finger between the straps. Long story short: no you do not decrease your grip strength by using our grip. Short answer: no! Whereas the grip feeling itself is more comfortable now, especially compared to standard cable machine handles and to most pull-up bars, this does not lead to a weakened grip strength. Rather, grip strength will remain unaltered. The only two things that will and should change with Angles90 grips involved are a) less joint stress (shoulders, elbows, wrists) and b) maximized contraction of your target muscle, your back. However, if your main aim is to focus on increasing grip strength, one out of our four grip methods can help you with it: The so-called forearm grip method consists in putting your ring- instead of your middle finger through the strap. In this way, your forearms will be engaged more.

While gymnastic rings are definitely also a great product, here are several differences: | You can only grab rings in one way. Our grips, on the other hand, offer different grip options. The ERGO grip option closely matches the natural curve of your hands, which makes it more ergonomic. | Rings are much bigger, and therefore less convenient to carry around. | Most importantly, the Angles90 grips can be attached to all kinds of pulling machines, cable machines, bars, and bands, which allows for a more natural ROM and a wider variety of exercises - not just for pull-ups.

A freely movable handle allows for a more natural range of motion which directly implies less joint stress. Our bodies were not made to grab horizontally aligned handles year in and year out in the gym. From a biomechanical perspective, our arms (slightly) rotate when they pull something. With the use of Angles90, you grab a handle that adapts to you and not the other way around. This helps your involved muscle groups absorb forces more efficiently, therefore minimizing wrist, elbow, and shoulder injury risk.

The grips were designed for pull exercises, because that is where the freedom in choosing different grip positions is missing the most (barbell deadlifts, pull-ups, rowing machines etc.). However, the handles are also attachable to cable machines for a better grip, like while doing Chest Flyes. With the help of our A90 Sling Trainer and A90 Resistance Band, you can do a lot of 'push' exercises too, just use the POWER+ method explained above on this page.

Angles90 allows you to train in a natural range of motion, which means that countless exercises can be performed more effectively and with less strain on the joints.  Our body is not made to move weights with fixed, rigid angles - at least according to numerous studies and the best coaches on this planet.From a biomechanical perspective, our arms should move freely during a movement in order to alleviate pressure from wrists, elbows and shoulders. This problem becomes especially clear during 'pull' movements like lat pull-downs, pull-ups, deadlifts and barbell/machine rows due to limited grip options - unlike chest or shoulder exercises. For example with a dumbbell press, you intuitively chose a range of motion that feels most comfortable on your joints and that uses your target muscle most effectively.

| So small it fits in your pocket | You would miss out on the ergonomic handle with the conventional sling trainer option | Do pull-ups (even without a bar) | Widen the sling straps and do dips | Set up your dip station | Use it as a weight belt | Use it as a (movable) squat rack - also for new barbell exercises | Use it as a hight-adjustable anchor for bands and pulleys

The maximum resistance is 550lb (250kg) per strap, carabiner, and metal buckle! This has been tested and certified by TÜV.The Angles90 grips, instead, are certified for 400lb (180kg) per handle.

Of course! Assuming that the door is stable enough, you can even perform pull-ups there. Please have a look at the following video which explains how to set it up: Door pull ups

There are two bands included in the package: Blue Band = 9kg/20lb Black Band = 18kg/40lb. You can obviously use them together too.

Just set-up your A90 Sling Trainer to a high bar or tree and connect it with your Resistance Band. This is also beneficial for the durability of your bands because you do not have to attach them to a rough surface.

Of course! Simply tie the bands carabiner to the lowest point of your Angles90 grip straps. Please have a look at the following video: Assisted pull-ups
