Conjugate periodization is nothing more that raising several abilities at once - it has NOTHING to do with changing movements. For example, most athletes, especially beginners, use some form of conjugate periodization: they raise their strength, hypertrophy, speed and conditioning at the same time. So we use running, box jumps/bounds/throws, lifting (differing the variables of each) to have a balanced program. Beginners do very well with this as they are essentially physically retarded in all areas - it’s only an ADVANCED LIFTER (not athlete) that usually needs separate blocks of each; although some athletes have somewhat specialized blocks where certain attributes are maintained.
100% of beginners do not need to dynamic work with a barbell as their intra/inter muscular coordination is painfully low. That is why jumping/throws are ESSENTIAL. As is sub-max work and calisthenics and running and landing and really basic GPP work.
I just hate to see the term “conjugate” aka CONCURRENT used improperly when supposedly talking high level programming. For more information, please read Supertraining.
