Do you know the difference between a compound exercise and an isolation exercise?
A compound exercise is an exercise that involves more than one joint.
An isolation exercise is one that only acts on one joint.
Squats create movement at your hips, knees and ankles and to some degree your spine. That’s a compound exercise.
A bicep curl only moves your elbow joint. So it’s isolating the bicep.
A list of common compound exercises
Chin ups
Deadlifts
Lunges
Press ups
Bent over rows
Squats
Dips
These should be your bread and butter when it comes to putting together a training plan.
A list of common isolation exercises
Bicep curls
Skull crushers
Lateral raises
Calf raises
However, with most of these isolation movements, it is possible to move from a secondary joint, so adherence to form is crucial. For instance, when things get hard during curls and skull crushers, your shoulders might get involved. So you need to limit that. That’s where a good personal trainer can be invaluable, because you could be loading the exercise but not seeing any results if it’s not performed correctly.
Hope that helps.
In a future post I’ll discuss why and when you might choose a compound exercise over an isolation, and why you might do one before the other.
Have a great day!
