30 day plank challenge

Okohme

Someone suggested this 30-day plank challenge to me I thought I'd give it a go. Now I know very little about strength/resistance training so I thought I'd ask here where maybe some people have some more specific knowledge and personal experience. Here's the challenge:
Day 1 & Day 2 = 20 seconds
Day 3 & Day 4 = 30 seconds
Day 5 = 40 seconds
Day 6 = REST Day <<< make sure you do rest, it’s as important as the workout itself!
Day 7 & Day 8 = 45 seconds
Day 9, Day 10 & Day 11 = 60 seconds / 1 minute
Day 12 = 90 seconds / 1 minute 30 seconds
Day 13 = REST Day!
Day 14 & Day 15 = 90 seconds / 1 minute 30 seconds
Day 16 & Day 17 = 120 seconds / 2 minutes
Day 18 = 150 seconds / 2 minutes 30 seconds
Day 19 = TAKE A REST
Day 20 & Day 21 = 150 seconds / 2 minutes 30 seconds
Day 22 & Day 23 = 180 seconds / 3 minutes
Day 24 & Day 25 = 210 seconds / 3 minutes 30 seconds
Day 26 = REST, you deserve it.
Day 27 & Day 28 = 240 seconds / 4 minutes
Day 29 = 270 seconds / 4 minutes 30 seconds
Day 30 = 300 seconds / 5 minutes!



My question; how is doing this ONE time a day for, well, 30 days, supposed to do much? Everything else I have seen is reps and such. I'm not saying it WONT work, I'm asking HOW it does, if it does.

It will help build abdominal endurance. Might be good for someone with back pain. Other than that, i don't see the point of holding a static plank for that long. Once you can hold for 30-60 seconds, i'd switch to more difficult plank variations.

If you're a newbie to strength training, i suggest following a proven, full-body program, instead of "challenges".
