For example, one workout you may want to do lateral lunges with mini-band ankle walks. Another workout you may choose rotational step-ups with the 4-way cable hip exercise. The activation, mobility, and flexibility exercises can be done more frequently and not necessarily as part of a stand-alone workout. There's no one-right way to incorporate these exercises, so don't be afraid to experiment.
When was the last time you got on your gym's abductor or adductor machine and got in a good workout? It's probably been a while. Both are machines that don't get a lot of use, and they are often the target of coaches' ridicule on those "useless gym moves we should all skip" lists. Perhaps rightly so, especially if you're hopping on those machines hoping for a slimming effect.
Before discussing different strength and mobility exercises, we should first look at activation exercises for your Gluteus Maximus (referred to as the glutes) muscles. The reason for needing to activate your glutes is simple—as a population, we spend way too much time sitting, and as a result, what happens is what noted spinal researcher Stuart McGill terms gluteal amnesia—your glute muscles can "go to sleep" and not function properly.
Meanwhile, it’s extremely common for non-life-threatening low back pain to be alarmingly severe and persistent — to have a loud bark! Your doctor may not appreciate how true this is, and may over-react to all persistent low back pain, even without other red flags. In most cases, you shouldn’t let them scare you. Being “freaked out” about persistent back pain is the real threat: it can make low back pain much worse, and much more likely to last even longer (a tragic irony).

Preventing hip flexor injury focuses on good flexibility, as well as making sure you warm up before you go full speed. Warm muscles are much less likely to be injured. So take the time to warm up and start slowly before you go all out. A good flexibility program will also help to reduce the tension on the muscles, and reduce your likelihood for injury.
Strong ligaments and muscles support the SI joints. There is a very small amount of motion in the joint for normal body flexibility. As we age our bones become arthritic and ligaments stiffen. When the cartilage wears down, the bones may rub together causing pain (Fig. 1). The SI joint is a synovial joint filled with fluid. This type of joint has free nerve endings that can cause chronic pain if the joint degenerates or does not move properly.

Work on strengthening all of your core muscles and glutes. These muscles work together to give you balance and stability and to help you move through the activities involved in daily living, as well as exercise and sports. When one set of these muscles is weak or tight, it can cause injury or pain in another, so make sure you pay equal attention to all of them.
