When you plank do you prefer to hold an extended arm plank (like the top of push-up position) or do you prefer to hold a forearm plank? Which is easier for you?
Forearm planks are soooo difficult for me. I'm lucky if I can hold that for 15-20seconds. However, I can hold the extended plank for much longer. If the forearm planks are difficult for me does that indicate I need to focus on improving my core strength or arm/shoulder strength? Or both? I'm wondering what type of weight lifting moves will help me improve.
Thanks for your advice!
