When these muscles are under constant tension because of ergonomics and habitual postural positioning, they may become tight and shortened. This can result in pulling forward on the lumbar vertebrae, creating hyperlordosis and causing the pelvis to tilt anteriorly. This is commonly seen in people who maintain a seated position for a prolonged period such as office workers, computer programmers, and others who find themselves sitting at a desk for hours every day. It is important to provide education on proper ergonomics, movement, and self-care to these individuals.
The hip flexor muscles flex the hip during swing. They are particularly important for initiating swing91 when walking at slow speeds. Without adequate hip flexion during swing, knee flexion is more dependent on hamstring muscle activity.59 Patients with paralysis of the hip flexor muscles attempt to advance the swing leg by either externally rotating the hip and using hip adductor muscles as hip flexors or by circumducting the leg.59,61 The effects of hip flexor muscle paralysis on gait are particularly evident when walking up stairs or slopes, which requires lifting the leg.
Too much sitting: You probably know it can contribute to serious health problems like obesity and osteoporosis. But did you know it also contributes significantly to back woes, including lower back pain in yoga poses? Fortunately, you can use your yoga practice to offset the effects of a sedentary lifestyle, relieve associated back pain, and set the stage for safe practice of intermediate poses like backbends.
Functional strength: Exercises designed to strengthen multiple muscle groups simultaneously. Instead of a single muscle exercise, such as as bicep curl, functional strength exercises, such as a push up, strengthen all of the muscles in the shoulder simultaneously. When you move normally, muscles work together, so it just makes more logical sense to exercise them together as well.
Chin-Ups. The chin-up is the easiest way to determine someone’s relative strength. If you can knock out sets of bench with your bodyweight but can’t perform at least 5 bodyweight chin-ups then it’s time to re-evaluate your priorities. Chin-ups are an excellent mass builder for the lats, biceps, and upper back so they should take the place of machine variations like lat pulldowns whenever possible.
A: Start with the calculations above but don’t be afraid to adjust up or down. Your metabolism and physiology will adapt to more food by trying to maintain homeostasis and regulate your bodyweight. Some may have to increase more than others but the number on the scale doesn’t lie. If it’s not going up, then you probably need to increase your calories.
