Can you recommend gluten free food? I just found out I'm allergic and it would be nice to have alternative choices!

I have always had a curvy stomach. It's just how i Am built i gain weight in my stomach. I want to have nice flat stomach with good abs. I have always been so scared to add exercises because i am worried it will just add bulk to my stomach making it look bigger. Is that a myth? what would be good too slim down my stomach without adding more to my mid section? I am not overweight and i eat pretty decent. I would just love to know if my fear is silly and untrue haha

the twist should be done on both sides to target the sides symmetrically, right? seems it is done only from right to left rotation

Hey Karina and Kartina!! I absolutely love you guys! You've helped me get my butt back in gear!! At 5'10" I was 179 lbs in late May and began my fitness/weight loss challenge to get back into shape. I'm not 158.5 lbs from working with you and working out on my own- hiking, running, biking, and other fun summer sports.
I'd love if you made some small changes, though-
Could you keep uploading videos? It seems like they all stopped coming onto your Youtube channel in early August. I miss your new workouts!! Please keep posting them!! Even if they're small. It would be so super appreciated. 
You're awesome!!!
