I can hold a plank for 20-30s tops, I think, far shorter after I did other work. I have some ideas tow get more Volume and effect out of a session:
- hold until perfect form is no more doable, rest 20 secs, repeat, repeat a few times
- set timer to maybe 45s, hold until perfect form is no longer doable, start again holding the plank after next beep, repeat a few times
- hold 10s, rest 10 s, repeat a few times
Of course the actual values for the times will be a matter of experiment. Are there other ways to achieve my goal? Which one should I pick, and why?
Edit to clarify: My goal is to strengthen my core for health reasons and to be stronger overall. I assume that short time holding plank = little training effect. Hence I'm looking for a structured way to get the most effect out of the short sets I can do.
