Welcome to day 10. I did close grip chin ups, DEEP decline parallette push ups, and paused squats. This was a fast, simple, and minimalist calisthenics workout to build fitness and improve body composition. I also discuss how you can utilize training frequency to dramatically improve your competency in a movement of your choice.
One of the most successful methods for improving repetition count is a method called "greasing the groove". This is an ultra-high frequency approach to training a particular exercise. Typically, you would select the movement you want to improve, like pull ups for instance, and perform about half of your maximum repetitions for multiple sets, several times over the course of the day. This gives you a TON of SUBMAXIMAL practice with the movement, and can result in some very rapid improvements in strength and endurance.
