Tried And True
2,100 Asanas By Daniel Lacerda is a great book whether you like to challenge yourself at home or whether you teach yoga and need a good reference guide. I use this book weekly to challenge both myself and my students.
Cleaning your mat is a must. So I recommend a mat spray. You can find tons on Amazon or at Target. I like the Asutra Natural and Organic Yoga Mat Cleaner that also comes with a microfiber cleaning towel.
I typically wear my Nike Studio Wraps for Barre but if I am going to a hot yoga class I love the extra grip these shoes give me.
