==Isometrics in combination with dynamic exercise==

Isometric training is rarely used by itself and it is usually incorporated into a wider training regime. For instance, an isometric plank may be incorporated into a plyometrics regime. In addition, when a subject performs a dynamic movement, supportive muscle groups can work isometrically. For example, if a person squats while holding a dumbbell in front of their chest, then their arm action will be relatively isometric, whilst their leg action will be dynamic. Such a relationship between an isometric hold and a dynamic movement is often found in weightlifting: participants commonly hold a barbell overhead with straight arms whilst straightening their legs as they stand up from a squat position. This allows for the legs to be primarily responsible for the lifting of the weight.

In most sporting contexts, however, the use of a pure isometric action is rare. In skiing, for example, the skier consistently maintains a crouched position. Whilst this may be considered to be an isometric hold, there is also an amount of dynamic movement as the skier alters how deep the crouch is during their travel. Thus, isometrics can be said to be involved in and supportive of the overall skiing action, even though it is not solely isometric in nature.

In weight training and calisthenics, it is often the case that one phase of the exercise is more difficult to perform than others. If the exerciser tends to fail at this point then it is referred to as a sticking point. An isometric hold may be incorporated to strengthen the exerciser's action at this point. For instance, a sticking point in a heavy back squat is usually the lowest position reached. An isometric hold can be adopted in this position in order to strengthen the lifter's ability to hold the weight there. Over a period of training this can help them to lift the weight more easily from this position and thereby eliminate the sticking point.<ref>{{cite web |last1=Brandon |first1=Patterson |title=Science of Lifting: Isometrics |url=https://www.elitefts.com/education/training/powerlifting/a-primer-on-isometric-training-for-strength-and-power/ |website=elitefts.com |access-date=25 September 2019 |date=11 September 2013}}</ref>
