Calculate backoff set weight, percentage, or starting weight from any two values, with RPE-based drop estimates and plate loading.
Backoff Set Formula
The following formula is used to calculate the backoff weight for a given initial weight and backoff percentage.
Variables:
- W_b is the backoff weight
- W_i is the initial weight
- P is the backoff percentage
To calculate the backoff weight, multiply the initial weight by the result of 1 minus the backoff percentage divided by 100. This will give you the weight to use for your backoff set.
What is a Backoff Set?
A backoff set is a technique used in strength training where the weight is reduced after reaching a peak set. This allows for additional volume and intensity without the same level of strain as the peak set. The backoff set is typically performed at a percentage of the initial weight, which can vary depending on the training goals and the individual’s capacity. This method helps in building endurance, improving technique, and reducing the risk of injury while still providing a significant training stimulus.
How to Calculate Backoff Set?
The following steps outline how to calculate the Backoff Set.
- First, determine the initial weight (W_i).
- Next, determine the backoff percentage (P).
- Next, calculate the backoff weight using the formula W_b = W_i * (1 – P / 100).
- Finally, perform the backoff set using the calculated backoff weight.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Initial Weight (W_i) = 100 kg
Backoff Percentage (P) = 20%
