Undersun Fitness’ Frequently Asked Questions

  • How do you use the workout calendar?

    To make it easy to follow the program we’ve created a calendar on the main page, after login in, with all 12-weeks of the program. The workout and rest days are already scheduled in for you, so all you need to do for each workout is click on the appropriate day. That will take you directly to your workout for the day. When you’ve completed the workout click the “FINISHED” button. Each time you log in you will be taken back to this same main calendar page.

  • How many days a week do you workout on the TA2 program?

    The TA2 Muscle Building Program follows a 5-day muscle building split, with each muscle group trained different days. The most effective schedule is 2-days in a row of workouts, followed by 1-day rest, then 3-days of workouts, followed by 1-day of rest, before starting the cycle again. This split allows for adequate recovery for all muscle groups. Here’s what it would look like:

    • Sunday: Off
    • Monday: Back
    • Tuesday: Chest
    • Wednesday: Off
    • Thursday: Arms
    • Friday: Shoulders
    • Saturday: Legs

  • Do I need to wear gloves when working out with bands?

    For the best grip, and to avoid wear and tear on your hands, we recommend using gloves when working out with resistance bands.  Look for gloves with padding the goes all the way to the edge of the palm, which is where the pressure from bands is placed. You may also want to use full-finger gloves as some exercises place more pressure on the fingers.

  • How big are each of the Undersun Resistance Bands?

    Each of the five different size bands are 41” in length, and 82” in circumference. The X-Light band is roughly ¼” wide, the Light is ½”, Medium is ¾, the Heavy is 1 ¼” and the X-Heavy is 1 ¾”. 

  • What does the name "TA2" stand for?

    TA2 stands for “Train Anywhere. Train Anytime”, and with the TA2 Muscle Building program, paired with Undersun Resistance Bands, you will have the freedom to do precisely that. Don't be fooled with all that flexibility though, TA2 is a true muscle building and strength program.

  • How do resistance bands compare to free weights?

    Resistance Bands have most of the same benefits as traditional free weights, and even a few advantages. 

    Let’s first let's look at how they are similar:

    • Both provide progressive resistance, meaning that as you get stronger you can progress to heavier levels of resistance in order to continue making strength gains (progressive overload).
    • Both allow for variable-speed, meaning that you can perform your reps at different speeds (both fast and slow) to create either more or less time under tension for each rep and set.
    • The last major difference is the free-range of motion or movement. Unlike machines where you are locked into a plane of movement, with both bands and free weights you can move freely in any plane.


    Now let’s dive into the advantages of resistance bands:

    • Unlike free weights where the resistance is fixed throughout the range of motion, in an exercise, resistance bands create what is called Linear Variable Resistance. The more you stretch a band, the more resistance it creates. This “variable resistance” more closely matches the natural strength curve of your muscles, where you are typically weaker at the start of a movement and stronger toward the end.
    • Bands also have Resistance in Multiple Planes. Free weights only create resistance in the vertical plane, as they resist the force of gravity. For example, with any chest exercise you have to lay on a bench in order to press the weight up. With bands you can do a chest exercise standing, sitting, laying down or probably even on your head if you really wanted to.
    • When using free weights, there are many exercises where you don’t get Resistance Through the Full Range of Movement. A great example is doing biceps curls. As you near the top of the range of motion, your arms are in a somewhat locked position, which takes tension off your biceps. Like we talked about with variable resistance, you want to get more tension at the peak of a movement, not less. When using bands you get maximum tension even at the peak of contraction.
    • The next benefit is one that it’s easy to dismiss, but in fact it actually may be one of the most important – and that is by training with bands you are far Less Likely to Cheat Your Reps. Let’s go back to our example of doing biceps curls. This is one exercise where we’ve all seen someone swing their body to get those reps. By swinging you are using momentum to help get the weight up, instead of forcing your muscles to take on the full load. With bands you cannot create momentum, so even if you wanted to swing your body it would be pointless. This forces you to use better form and make your biceps do the work not your low back. Another added benefit of this is that with less cheating (which means bad form) it drastically reduces the chance of injury. Remember that progress isn’t just about moving forward – it’s also about not moving backwards, which is exactly what happens when you get injured.

    The last two benefits of bands over free weights are simple. Bands are light-weight and portable,which means that you are no longer confined or limited to just training in the gym. Now you can take your workouts anywhere you want to go (and won’t ever have to wait for someone to get off a bench)and since you don’t have to go to the gym, you can also potentially save a ton of money on gym memberships. You would be blown away at the statistics on what Americans spend on gym memberships each year.

    Here's a quick reference chart of how resistance bands stack up against free weights:


  • What if one of my bands break?

    Under normal circumstances, your Undersun Resistance should not break, but considering they are made from natural latex it can happen, especially if not used properly. In most instances, when a band breaks, it is due to repeated over-stretching of the band, or damage caused from a sharp or rough edge at the anchor point. Any breakage due to faulty manufacturing is covered in our 1-Year Limited Warranty. Please contact Customer Service if you experience a broken or damaged band.

    Over time the natural latex in the band can be damaged due to oxidation. To avoid injury please inspect your bands for any damage, before each use. If you notice rough edges, nicks, or pitting please make sure to replace your bands immediately.

  • What bands come in a set?

    Each full set of Undersun Resistance Bands comes with 5 different levels of resistance, from X-Light, Light, Medium, Heavy and X-Heavy. These are the 5 most frequently used resistance levels, and when paired together you can create countless levels of resistance, for any exercise.
