At the same time, this also doesn’t mean that primary compound exercises can never be done for more than 8 reps, or that secondary compound exercise can’t be done for 5-8 or 10-15 reps, or that isolation exercises can’t be done for less than 10 reps. Everything can be done in every rep range. However, these are the rep ranges that each type of exercise is best suited for, and where it should ideally be done most of the time.

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.
I’m 6 foot and 154 pounds and I’m thinking of using this diet to bulk up before I do a cut to shed body fat for a more lean look. How good would this diet be to maintain body fat while building muscle and how much muscle could you expect to put on. Thanks. I do not want to gain that much body fat while bulking and if possible I would just like to maintain my current body fat while bulking.
However, if you increase the demands you are placing on your body by increasing the weight being lifted, lifting the same weight for additional reps, or just doing something that increases the demands that your body needs to meet, then your body will have no other choice but to make the changes and improvements necessary for it to adapt to this environment and remain capable of performing these tasks.

As I mentioned earlier, the exercises that come first in your workout (aka primary compound exercises) should usually be done in the 5-8 rep range. Exercises in the middle (aka your secondary compound exercises) should usually be done in the 8-10 rep range. Exercises done at the end of your workout (which is typically where isolation exercises belong) should usually be done in the 10-15 rep range.


There are nutrients within these fat sources which decrease inflammation, improve mental function, improve eyesight, and give you healthier skin, hair, and nails. When I'm crushing the iron in the gym each day, my goal is to be strong and big, but also healthy and mobile. To get that way, I eat all of these generously on a regular basis, and I also take omega-3 supplements daily, in the form of fish oil or krill oil.
