Exercise Training modes refer to a variety training methods designed to achieve various physical fitness results. These can include but are not limited to strength, endurance, flexibility and cardiovascular health. Each method can focus on a specific type of fitness results or a combination of results.

Examples of exercise training modes include isokinetics, isometrics, T.U.T. (time under tension), suspension, plyometrics, oscillating wave, elastic band, flexibility, functional, Hiit, Tabata, yoga and more.

The T2 Iso-Trainer offers the greatest number of on-demand training modes ever available in a fitness device.

Following are definitions of current popular training modes with a detail of how the T2 Iso-Trainer achieves or enhances them:


Isokinetic exercise is defined as maximum effort under controlled speeds using variable resistance. Normally, in order to create controlled speeds, very specialized exercise machines are required. They cost thousands of dollars and are usually found in specialized sports training or rehab facilities. Isokinetic machines control the speed of an exercise by fluctuating resistance throughout the entire range of motion. Your speed remains consistent despite how much force you exert.

The T2 Iso-Trainer uses Body Fight in conjunction with timed movement and our patented housing to make isokinetic exercise possible without expensive machinery. The effort put into the exercise movement is maximal throughout the entire range of motion - training the muscle from start to finish as effectively and efficiently as it can be trained. The result is greater muscular activation, faster muscle fatigue and dramatically shorter workout times. Isokinetics combined with the T2's On the Fly Intensity & Exercises Changes makes it a ground breaking and unprecedented exercise device.


Isometric exercise is the static contraction of a muscle without any visible movement in the angle of the joint. Sort of a freeze and squeeze action.

The T2 Iso-Trainer allows you to instantly incorporate isometric training on the fly by simply freezing your movement under maximum effort at any angle throughout the entire range of motion of an exercise. Certain compound exercises allow for opposing muscles groups to be engaged in the isometric. A capability unique to the T2 Iso-Trainer!


This is our very own newly defined and trademarked training mode. It combines all the benefits of T2 Isokinetics with elastic resistance using our custom T2 Power Bungee. In Iso-Elastic mode the T2 is incredibly versatile and can be used for an unlimited number of exercises and training modes including suspension training! Variable resistance exercise is not only adjusted by speed via the T2 Housing, it can be precisely adjusted and automatically controlled with elastic tension. Fine tune the resistance simply by stretching or relaxing the elastic tension. An unprecedented feature of the T2 Iso-Trainer.


Suspension training refers to an approach to strength training that uses a system of static ropes or webbing called a "suspension trainer" to allow users to work against their own body weight performing various suspended body weight exercises with gravity acting as the resistance. The more your weight is fighting the gravitational pull the harder it is to perform the exercise. This mode of exercise has been performed since the 1800's and more recently embodied in products like the TRX Suspension Trainer or Monkii Bars suspension trainers.

Every suspension training exercise ever conceived can be performed with the T2 Iso-Trainer but with instantaneous access to and inclusion of more effective and beneficial Isokinetic and Iso-Elastic exercises. This allows for truly astounding possibilities and exercise flow rendering single function suspension trainers obsolete. No other device on the planet has this capability.


Elastic band training is simple and versatile. The more the elastic band is stretched the harder the exercise gets. Like dumbbells, barbells, or other free weights; elastic resistance bands provide external resistance that your muscles have to work against.

Elastic core training evolved from simple torso twist and rotational exercises that can be performed without resistance or with resistance such as bands, cable machine, medicine ball or elastic band attached to a stick or ball as embodied in the TRX Rip or Monkii 360 trainers. It works the entire body in a very profound way engaging the entire abdomen, oblique muscles as well as the chest, back, arms, and shoulders when coupled with resistance.

Every elastic band and rip training exercise ever conceived can be performed with the T2 Iso-Trainer but with instantaneous access to and inclusion of more effective and beneficial Isokinetic and Iso-ElasticTM exercises. Elastic Core Training with the T2 Iso-Trainer automatically engages not just the core but the entire body. You will find core work is incorporated into your training without having to think about it.


Time Under tension (TUT for short) is commonly used in strength, conditioning and bodybuilding for muscle gain. Also known as “tempo training” or “super-slow training”. It involves long slow reps while the muscle is under load or strain.

The T2 Iso-Trainer can instantly work under the T.U.T. principal. With maximum effort being applied to each repetition it’s simply a matter of extending the rep timing. The T2 allows you to deliver a max effort with each rep with accommodating resistance. Bands (which work under an elastic stretch tension principle) or free weights, (which use isotonics) don't offer maximum efforts with accommodating resistance. The T2 trains the muscles and body at their fullest potential throughout the entire range of motion


Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping.

The T2 Iso-Trainer allows you to incorporate Isokinetic, Iso-Elastic and elastic movements while performing plyometric movements. Prepare yourself!


Flexibility training encompasses stretching exercises for the purpose of increasing the range of motion of a joint and its surrounding muscles during a passive movement. Passive would mean that no active muscle involvement is needed to hold the stretch.

The T2 Iso-Trainer allows for instant and deep flexibility and stretching before, during and after exercises. This is especially handy when you find yourself so winded from using the T2 that you just need a moment to rest and collect yourself.


Functional Fitness Training is a classification of training that prepares the body for real-life movements and activities. Movements such as squatting, reaching, pulling, and lifting will be made easier with functional fitness integrated into your exercise routine.

The T2 Iso-Trainer provides the apex of functional fitness training in new and profound ways by making isokinetics, isometrics, plyometrics and all our modes of training instantly available to you. Easily mimic specific movements like swimming strokes and flutter kicks, baseball swings and throws, football throws, surfboard paddling, golf swings, tennis strokes, even yoga as well as mixed martial arts ground fighting techniques (check out our clip of MMA pros and our beta testers UFC Champ Cris Cyborg and Victor Rosas training with the T2)


High Intensity Interval Training (HIIT) also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is a form of interval training. A cardiovascular exercise strategy alternating short periods of intense anaerobic exercise with less intense recovery periods, until one is too exhausted to continue. These intense workouts typically last under 30 minutes, with times varying based on your fitness level as well as the intensity of the session.

With the T2 Iso-Trainer you can create unlimited numbers of HIIT workouts that involve all training modes and can engage more of your body without ever having to let go of the handles. You will quickly discover that HIIT workouts with the T2 Iso-Trainer are the most dynamic and free flowing you will ever experience.

How much resistance can the T2 Iso-Trainer produce?

The simple answer is limitless resistance. The T2 Iso-Trainer is a Body Fight System. You provide the resistance and the T2 housing MULTIPLIES YOUR RESISTIVE EFFORT. It can be measured with a dynamometer as we illustrate in our "T2 housing vs. a Pulley" video but the max measurement would be different user to user. Based on the video demo, if you provided a mere 10lbs of resistance the T2 housing would double that to over 20lbs on the opposing side. This increases exponentially as you increase your resistive effort. You can easily generate enough resistance through the housing so that you can't even move through the motion, converting the exercise into an isometric with no plates, bands or pins to change.

What warranty does the T2 Iso-Trainer come with?

The T2 Iso-Trainer Exercise System comes with a general warranty of 1 year from date of delivery to be free from defects in materials and workmanship. The warranty does not cover normal wear and tear of woven nylon straps, handles, elastic bands or bungees. The T2 metal die-cast housing comes with a Lifetime Warranty. Customer is responsible for shipping costs of warranty covered products to T2 Fitness Products Inc. We will ship replacements for warranty qualified parts free of charge. Before returning or filing a warranty claim please contact for a return authorization and the return shipping address.

How much does the entire kit weigh?

The entire kit is just over 3lbs (1.36 kilos).

What is the weight capacity of the T2 Iso-Trainer?

The T2's weight capacity is 350lbs (159 kilos). Keep in mind that the capacity of your anchor point is a critical safety factor and may be less than the capacity of the T2. Some interior doors are weaker than others. To avoid serious personal injury always check that the anchor point is secure and able to support your body weight and that all straps and hardware are in good condition.

My handle inserts are loose and fall out! What should I do?

Looks like we goofed on the diameter of the wooden handle inserts. Some of our customers have mentioned that they slip out after a while. There was a variance between the inside diameter of some of the handles and we need to remake this part with a slightly larger diameter (+2mm) to create a tighter fit for any tolerance variance. It'll take a little while to get them in but we'll replace any that are giving you problems. A quick down and dirty fix in the meantime: Wrap masking tape around the middle of the dowel a few times to increase the diameter. Our apologies for the inconvenience. We'll make this right! Please try our handles without the inserts as well. Most of us on the team prefer the Flex Handle mode without inserts. The T2 Fitness Team
