In isolation exercises, it’s generally safer to use free weights and cables. To work the pectorals, for example, you could perform bench presses or dips in the first session, and dumbbell flyes in the second.Ĩ. Performing the isolation movements in the first session would significantly reduce the amount of weight you could use in compound exercises performed later that day. If you have the time to train twice a day, focus on the compound movements in the first session and the isolation movements in the second. When training twice a day, compound movements are better for the first session. To work all areas of the strength curve, you could also include the lean-away lateral raise with a dumbbell (top range) and the one-arm lateral raise with low cables (bottom range).ħ. For example, the one-arm lateral raise with dumbbells is a good exercise for the medial deltoids, but the primary stress is felt in the mid range of the movement. Although workouts that use primarily isolation exercises require more exercises be performed, you still need to plan carefully for optimal results. Workouts using isolation exercises require more variety. Also, on the last rep of concentric failure, with the barbell overhead you can lower it slowly, thus prolonging the time under tension to produce a powerful eccentric contraction.Ħ. For example, when performing the standing barbell overhead press, when you reach a point of failure you can use your legs to kick the barbell through the sticking point to overload the end range. With many compound movements using a barbell you can often adjust to changes in the body’s natural strength curve by using “cheating” methods. Compound movements often provide a better match between the strength curve and the resistance curve. As an example, studies using EMG (electromyography – a method of measuring the electrical activity of muscles) have found that Scott curls produce greater involvement of the elbow flexors than standing barbell curls.ĥ. Exercising from a seated position conserves neural drive that otherwise would be spent stabilizing the body in a standing position. Isolation exercises are often more effective when performed from a seated position. A better choice would be a 45-degree back extension, as the resistance is greater at the start and mid-range of the movement.Ĥ. With a horizontal back extension the most resistance is also at the top range, so this exercise offers little benefit to improving your squat. For example, in a squat you are strongest in the top range of the exercise, so a supplemental exercise should give you the most resistance in the bottom range. The resistance curve of isolation exercises often does not match the resistance curve of compound movements that involve the same muscles. For advanced trainees, a good general guideline is to change isolation exercises every six training sessions.ģ. Isolation movements, in contrast, focus the stress on one area of the body and as such need to be varied more frequently to avoid overuse injuries. Exercises such as squats and cleans can be performed year-round, because the stress of these compound exercises is distributed over many muscle groups.

Compound movements are usually less stressful on the body than isolation movements.

In contrast, increasing your squatting poundages can significantly increase performance in leg extensions and leg curls.Ģ. For example, performing a training cycle of leg extensions and leg curls does not contribute significantly to improvements in squatting ability. This is one of those times that the sum of the parts doesn’t equal the whole. Isolation movements often don’t transfer well to performance in compound exercises. Here are eight guidelines to use when deciding between isolation and compound movements.ġ. When it comes to program design, it’s critical to select the most appropriate exercises to achieve your goals for each training cycle. So how do you choose which type to use in your own program? Practitioners in the fields of rehabilitation and functional training promote the use of both compound and isolation exercises. The strongest and most powerful athletes in the world do compound movements such as squats and power cleans, while the biggest bodybuilders in the world spend considerable time on isolation exercises such as preacher curls and seated calf raises.
