Well, these two programs are a bit tricky. Like what you have said that both seem to target the hip area and lower back area. You are correct but to know the difference between the two, you must also identify where is exactly the pain.
In many cases, it wasn’t the lower back or the hips that were causing the pain for some people. It was injury and weakness in a muscle that’s located in the same area as the hips and lower back, called the Gluteus Medius.
Since this muscle is located in the same area, it was believed that it was their hips or back that hurt, and didn’t realize that the answer lies in this muscle called the Gluteus Medius.
While the Unlock Your Hip Flexors program is suitable for you if you're currently suffering from inexplicable back, hip, or joint pain and tight hip flexors. This program also targets the psoas muscle that creates a neutral pelvic alignment, stabilizes the hips, supports the lower spine and abdomen, supports the organs in the pelvic and abdominal cavity, and gives you greater mobility and core strength.
