A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back, and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
To begin, place the top of one foot on a weight bench (or a chair) and step forward with the other foot out in front of you, similar to a lunge position. Make sure that the front foot is positioned at least at shoulder width and it is far enough away from your body that your knee will not come over your toes when you perform the squat. Put your hands in front of your body (or overhead to make it harder). Perform a “single leg squat” by bending the front leg. The knee of the leg that is up on the bench will go towards the floor. Get it as close to the floor as you can. Do not let the heel of the front foot come up off of the floor. Keeping your heel down will ensure that you engage your glutes and hamstrings in this exercise. You should feel the tension in the hip flexor of the leg that is on the bench when you perform this exercise (you will also feel the muscles of the front leg working). It is important to keep your torso upright throughout the full range of motion. As you go down into the squat, the hip of the back leg is going into extension, which will stretch the hip flexor as well as strengthen it as it stabilizes the hip throughout the range of motion.
Your questions kinda ties everything together. You are already aware of “nutrient density” which is AWESOME. This is important because I believe one food may be more “healthier” over another due to its “nutrient density”. The other food is still healthy because it still contains nutrients, but the nutrients could be more dense…so this is why I think one food may be “healthier”, while the other just isn’t as “healthy”. It’s not, not healthy.. Make sense?
If you’re a beginner, you should train with three full-body workouts per week. In each one, do a compound pushing movement (like a bench press), a compound pulling movement (like a chinup), and a compound lower-body exercise (squat, trap-bar deadlift, for example). If you want to add in 1–2 other exercises like loaded carries or kettlebell swings as a finisher, that’s fine, but three exercises is enough to work the whole body.
Increase your caloric consumption. Keep a log of the number of calories you eat, and use the average of those numbers to estimate your daily caloric needs. Then, multiply that number by 1.1. Make sure your calories are coming from a variety of healthy, minimally processed foods to provide quality nutrients for muscle-building. Try to get 30% of your calories from proteins, 50% from carbohydrates, and 20% from fats.
I say make the 5th rep hard, but when I lift heavy, I like to stick with 4–5 reps. I feel if something is truly heavy, we won’t be able to hold onto it for as long, therefore, 4–5reps is my time frame for failure when lifting heavy. Again, if I need to keep doing reps to reach failure, then it’s too light. When I lift light, my time frame for failure is around 12–15 reps. If I need to do more reps to feel the fatigue of failure, then it’s way too light.
Unfortunately, it’s hard to significantly increase levels through food alone. That’s where supplementation comes in. For instance, in one 12-week study of resistance-trained individuals, taking HMB in tandem with a high-intensity lifting routine significantly improved muscle strength and size compared to lifting alone. Plus, in the off-chance that you push yourself too hard, HMB helps prevent the effects of overtraining—including muscle loss.
