Thus, there's a big difference between cheating on the last rep or two
of isolation exercises like the dumbbell curl and lateral raise versus a barbell pull or press.
Aspe et al. (2014) compared a
number of isolation exercises including the sit - up, side plank, swiss - ball jack knife, and straight leg sit - up.
The idea is to use compound and neurally - demanding exercises like bench press, shoulder press, squats, deadlifts and rows instead
of isolation exercises for different body parts.
Instead of isolation exercises do compound exercises, these work one than one joint and muscle group, so squats, lunges, deadlifts, bench press, push ups, pull ups these all work more than one muscle group at a time, meaning you can work out more of your body in less time.
Sure, everybody wants impressive arms, but once you get them to grow with the help of heavy compound movements, the next step is carving out detail by a
ton of isolation exercises, which can be quite a snooze-fest.
These are the exercises that allow you to use the most weight, allow you to add weight the most often (aka the progressive overload principle) and will add more muscle to your body than any
combination of isolation exercises ever will.
In this phase, you'll be harnessing the power of an increased
amount of isolation exercises to help round out your physique and give that seriously JACKED look you've always wanted!
It is only justified for a beginner to do this movement is if it's one of a
handful of isolation exercises done «for fun,» which encourages adherance to training.
Typically, if you perform many compound exercises for one muscle group in one, your muscles tire easily, and you will see less benefit on the exercises you perform 2nd, 3rd, 4th, etc — hence the reason why so many routines are
full of isolation exercises.
Schanke et al. (2012) compared a number
of isolation exercises with the barbell bench press, including the dumbbell fly, pec deck and incline dumbbell fly.
For example, he showed me that too much of my routine
consisted of isolation exercises (curls, calf raises, etc.) and that not enough of it consisted of compound exercises (dead lifts, bench press, etc.).
I would actually say that if you could measure the amount of testosterone produced by the above two activities that the 4 minutes of bench press would produce far less testosterone than the 4
minutes of isolation exercises.
Now, we all know that most women have a mystical fear of approaching the weight room and usually stick to the treadmill or perform endless
reps of isolation exercises that target small muscle groups, both of which are not a very good choice when it comes to boosting the metabolism, building lean muscle and shedding fat.
If novice trainers instead choose to start a routine filled with a
bunch of isolation exercises for the arms and other minor body parts, it has the effect of «watering down» their focus.
The triceps is also highly active in a number
of isolation exercises.
