There are many great core challenges available.
Do planks even do ANYTHING? (Build muscles, strength, toneing, ect.?) I think that it's prety much useless and that your just hurting yourself.
I don't see how people can't do the 2 min plank. EASY CORE WORKOUT
Planks are definitely worth it if you do them correctly.
Well than I can just flex all day long and get buff.
It's called isometrics! And yes, it does build strength.
Yeah planks are great and pretty much good for everyone as the risk of injury is low compared to many other core exercises which can hurt your back
I appreciate you guys correcting me without being nasty.
I can see from your profile that you do mainly calasthenics - me too! Calasthenics are a great way to build strength and stamina.
