I'll be honest with you: the progressive overload and Workout Enhancement Tool structure for calisthenics training is not nearly as cool as weight lifting.

That being said: you still HAVE TO focus in on progressive overload while using SHJ Calisthenics Workout Routines.

Your Workout Enhancement Tool programs you progressive overload by forcing you to scale up your reps week to week, but there are other ways to scale up as well.

How To Scale Up Your Calisthenics Training

Here are a few ways to scale up your calisthenics training (including what you already know):

Consistently increase the amount of volume you perform: This can be done by increasing the amount of reps per set, or even by adding in more overall sets to increase the total volume within the workout.
Scale up the type of calisthenics exercise you're doing by moving to a more difficult variation of it. I will list examples of this below.
Add weight to your calisthenics training: Another way to scale up is to add weight with a weighted vest or even a weighted belt. While you will still be performing calisthenics movements it will allow you to add in the styles you've learned to use with your weight training progressive overload tactics.

Examples of Scaling Up your Calisthenics Movements [Variations]:

Scale your Knee Push Ups or Pause Push Ups to Regular Push Ups

Scale your Regular Push Ups to Explosive, Wide to Close, Diamond or other Push Ups Variations that are more difficult

Scale your Assisted Pull Ups or Pike Push Ups to Pull Ups

Scale your Pull Ups to Wide Pull Ups, Slower Pull ups, Typewriters, or more
