A NOTE ON CYCLES: NO CYCLE ADVICE:

You don't NEED CYCLES to progress, they help but they are not some magic formula. You need to workout progressively on a regular basis, that is all that is needed in the final analysis of weight training.

In many ways cycles complicates training unnecessarily. Bodypart recovery also does this. For some people keeping things simple is best. Forget about bodypart recovery. Forget about cycles.

Training is simple. Don't complicate it. Here is the NO CYCLE ADVICE:

FORGET Bodypart recovery: Your body recovers as an organism. It doesn't know an arm workout from a leg workout, except that the leg workout is a lot more taxing on the entire organism. With that in mind train with a "total body" mindset. If you are tired from legs, don't do arms or anything else till you recover. Train with a mind toward total body training and recovery. Do uppers one day and legs 2 to 3 days later, repeat forever.

FORGET cycles: Train hard for 6 to 10 weeks then take a week off or switch to light workouts. Lift progressively. Slowly add weight or reps to your exercises over time using linear progression. Forget cycles, just lift and get stronger.

Body part Recovery

I realize there can be confusion as to how to integrate this blasting of one body part into your schedule. Here is how it works. Let's say it is week one of your monthly cycle. It is the strength training phase of your yearly cycle. During week one you are not supposed to train TOO HARD in order to prepare yourself for the really tough training to come in weeks 2 and 3 as you increase the intensity and the weight. You are scheduled to blast your shoulders...what do you do? Go off course and lift super heavy? Blow away the shoulders the first week of the month and possibly derail the entire cycle process for that month? No Way (You are supposed to wait until week 3 to lift at your max) Do you hold back?
The answer is train as hard as possible within that phase of the cycle, but hold back on the bigger picture of training your entire body. Wait until week 3 during your shoulder training to lift your maximum weight,however; you still want to blow away the shoulders during this week by giving them special intensity.
Let's say it is Week one of your monthly cycle during the strength- training phase, of your yearly cycle-you would NOT lift super heavy and you would NOT train until failure (following the general rules of week one workouts) but you would blast your shoulders by raising the intensity. The best way to train without taxing the glands and your recovery--(save it for week 3) is to train without any break between exercises for several sets. Don't over train or overload your body but for 10 to 15 minutes blast your shoulders. Line up 4 exercises and do them as a circuit. Do lots of reps. Do supersets. Do slo-mo reps. Do 1/2 reps on the shoulder press followed by laterals until your arms go numb.Let us change it up..let us say it was week three of your monthly cycle. It is the strength training phase of your yearly cycle and your back is scheduled to be your peak body part. This was a good move as back training can be very taxing and your body will need a good part of the following week to recover properly. You would rest between sets and try to lift as much weight as possible for all-out sets. This is a classic power routine. Do 3 to 5 heavy sets of your primary exercises and go home. Your power movements such as super heavy rowing, deadlifts, and chins are all great. Use as heavy a weight as possible.
