I have lifted weights (barbell and kettlebell) for 20+ years. I needed a program that kept me strong enough for what life threw at me but didn’t leave exhausted for what life threw at me also. This was that program. It made aches end. It tightened up loose spots and loosened the tight spots. I can hang with the 20 year olds at work all day and even shock them with some things we have to lift and carry. This program is safe for the injured. I have a rebuilt shoulder, knee, and back from martial arts and hard physical work. I enjoyed the training and will rinse and repeat. BW training isn’t linear you will get something new every cycle. This is the closest you will come to a complete holistic system of training.
