Have you ever noticed that your trainer changes the number of reps in your workout mainly based on your training goals, not just your fitness level? It’s true—your trainer adjusts your reps to help you reach your goals.
Here’s a brief description of reps and how they work:
A repetition includes a concentric and an eccentric phase of movement for the muscles involved. Each time you lift and hold a load is counted as one repetition or rep. Breaks can be added between the contraction phases.
How many repetitions you do of a particular exercise has a major impact on results. The relationship between reps and muscle development is as follows:
In this example, each rep must last six seconds—that is, three seconds of contraction and three seconds of release. The nuances between different contraction times will be explained in future columns.
The number of reps is critical to achieving your goals, so make sure you talk to your certified trainer to discuss your needs.
Have a great workout!
