I've been doing calisthenics for the past year or so, and lately I became quite frustrated as I hit a 3+ months plateau on my l-sit (this is what it looks like in case you're not familiar: https://www.calisthenics-gear.com/calisthenics-exercise-list/#tab-con-34).
I've been stuck on doing it for under 5 seconds. So much so, that I stopped working out for about 2 weeks.
But lo and behold, when I tried again this week, I could hold for over 10 seconds!
So I suspect I've been overtraining. I work out 4 days a week, medium intensity.
What is the ideal pattern of training for calisthenics- should I train 4 days a week and occasionally take 2 weeks+ breaks? Or train only 1/2 times a week, but go extra hard during those workouts?
