# 燃烧卡路里大作战 # Drop, open day 5 💕This is a new yoga ball I bought at amazon.✌. The original price is 24.99+. I bought it for about $13. 💕 Haven't I been working out all the time recently. I usually use the yoga ball in the gym. This time I just bought one for my home use on prime day. I bought this one for 55cm. I bought it according to the size they marked. I feel that I bought it a little too small. 65cm is estimated to be about the same. It comes with an inflatable one. I stepped on it a few times and didn't move 😂😂😂. I still let my husband do it. 💕I don't know much about the brand of the yoga ball. I bought it from the review on amazon. I feel that this brand is still worse than the gym. Too much inflation. I'm afraid it will explode 😂.
