Learn Your Limits - Carving is an intense exercise, especially the first time you try it. It is not unusual to feel sore after your first carving workout. This is a tough exercise and it will take time to build your core. Take It Slow - Carving is not about speed, it's about slow and controlled muscle contractions. Pace yourself. Moving slowly lets you focus on maintaining proper form and getting results. Package Include : 1 Unit x AB Carver Pro 1 Unit x Knee Pad
