Danica Osborn on Instagram: "Bis and Tris Oh My! Give this Bicep and Tricep workout a go if you want stronger arms. 🔟 reps of each 3️⃣x through. I’m using 12lb/5kg dumbbells but listen to your body. That means you can do fewer or more reps, lighter or heavier dumbbells, and less rounds through, if needed. As I tell my classes, YOUR workout, YOUR body, YOUR goals. Let me know how those arms feel after these! 😜"
