Undersun Fitness’ Frequently Asked Questions

  • Can resistance bands build muscle just as effectively as free weights?

    Not only can resistance bands build muscle just like traditional weights, they even have some advantages over free weights, other than just being portable. Unlike free weights where the level of resistance is fixed throughout an exercise, resistance bands create Linear Variable Resistance (LVR), meaning that the more you stretch them, the more resistance they create. 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. This allows for stronger peak contractions, and therefore more potential muscle growth.

  • How does the program work?

    The TA2 Muscle Building Program follows a time-proven muscle building split, with each muscle group broken up into different training days. Each workout consists of multiple exercises per body part, with a strategically designed set and rep structure, to maximize mind-muscle connection, elicit peak muscular contractions, and develop explosive strength and muscle growth. Every 4-weeks the program progresses, attacking the muscles with new angles, and new exercises, utilizing resistance bands only.

  • 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


  • How long is each workout?

    Most of the workouts are 4 total exercises, with 4-sets per exercise. If you keep your rest between sets down to 1-minute, you should be able to complete each exercise in 6-7 minutes. At 4 exercises this puts your total workout time at roughly 30-minutes. It’s a misconception that you need to spend an hour plus in the gym to build muscle. Whether you’re training with resistance bands, machines or free-weights, if your workout is more than 40-minutes, that you just means you’re resting too long.

  • 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 long is the rest between each exercise?

    To shorten your workout time, and keep the intensity high, it’s recommended that you only rest 60-seconds between exercises. This is going to keep your heart-rate elevated as well, which will have a calorie burning effect. If you need more rest time, go ahead and take it. As you progress through the program just incrementally shorten your rest periods and try to get down to that 60-second mark.

  • How long is the rest between sets?

    Just like the rest between exercises you want to keep your rest between sets to 60-seconds.

  • How many sets do I do?

    For each exercise, in the TA2 Muscle Building Program, you will be doing 4 total sets.
