You would use the expression d'accord when you agree with something. For example: Oui, je suis <u>d'accord </u>avec vous. - Yes, I <u>agree </u>with you. It can also translate as sure, okay, of course, naturally, alright, etc.
My family has bought a treadmill. Its very useful especially during times like these. I can both stay home and fit. I've also been doing yoga. It's very calming and I can stretch out any place that feels stiff. That helps throughout my day because i do move a lot
