Beach muscles and Olympic lifts draw more attention. But the many little stabilizer muscles around your shoulders, hips, and midsection — collectively the core — provide a strong foundation. Challenging the stability and mobility of these key muscles with medicine balls, physioballs, mini-bands, and rotational movements (lifting, chopping) pays huge dividends.
When it comes to building muscle, your body only knows or cares about the tension, fatigue and damage an exercise is generating… not the type of equipment you were using when performing that exercise. It really couldn’t give the slightest crap about that. For this reason, ALL types of exercises and ALL types of equipment are capable of stimulating muscle growth.

(1) Water - I drink this all the time. Mainly in the morning. Doesn’t it make sense to hydrate upon waking up? I use to get nauseous, but that was because of a poor “diet”/food choices. Now, it’s like a filtering fluid at this time of day (morning). I drink it all day, but I have like 1 water bottle every hour. It’s easy to remember and to do (well, for me). We should aim for around 100oz of water, consuming all this in one time would suck. So “timing” water (which is a nutrient) is considered “nutrient timing”.
Hook a velcro cuff to a low cable pulley and then attach the cuff to your right ankle. Face the weight stack from a distance of about two feet, grasping the frame for support. Keep your knees and hips bent slightly and your abs tight, contract your right glutes to kickback the leg. Slowly bring your working leg forward, resisting the pull of the cable until you reach the starting position. Repeat for required reps, then switch legs.
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.
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?
Remember my special answer: here it is… MOUTHTAPERS exist. People out there will tape their mouth closed during sleep so that they can breathe their nose. Even during the day sometimes. Why? Because the nose is directly connected to the diaphragm while the mouth is connected to the chest. Sure, increase chest mobility and your lungs may be able to expand more which will allow more air to be held, BUT HOW CAN YOU HOLD THAT MORE AIR IF YOUR DIAPHRAGM is weak? You won’t. So everything I just talked about must be done through the nose. Notice yourself breathing with your mouth and SWITCH right away. It takes work and energy. How you breathe during the day rolls over to how you breathe during the night.
