thinking of joining the gym

C
Alright ladies, I'm officially sick of this post partum body. Baby is EBF and doesn't take the bottle so joining the gym is a challenge but I've found a gym that had onsite childcare for 45 minutes at a time. I can drop her off right before my workout, pick her up right after, and if there are any problems they can come get me.
Anyone try this? How did you feel? I'm nervous to leave her with strangers
