Am I missing something with the block? I've played two sessions, in my first one I completed the entire first world without really losing any health and found it relatively easy.
On the second world I upped the difficulty slightly and basically died straight away, only making it to the second level in the world. I didn't find it too difficult or get too out of breath whatsoever, energy wise I could have played through the whole world, I just lost all my hearts almost immediately.
I don't really get how the ab guard works, I hold it so tight that the ring is basically touching each other and hold it for how long it tells me to, and sometimes I get Great, sometimes I get Good, sometimes I get Ok etc - without anything really being noticeably different in how I've done it. What's the criteria for a perfect block that keeps as much health as possible?
Outside of this I'm really enjoying the game and have had a great workout already
