The three main types of isometric exercise are isometric presses, pulls, and holds.
This is in contrast to isotonic contractions, in which the contraction strength does not change, though the muscle length and joint angle do. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. Once you can hold it for a minute, either move your arms and leg up and down under control for the duration of the set, or hold a dumbbell in your top hand.The 'side plank' is a variation designed to strengthen the muscles on the side of the core, such as the obliques.Īn isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. Hold this position without falling over. Start by doing sets of 15 seconds each side, then gradually increase the time you spend in the hold, working each side equally. Raise your hips, keeping your core braced, then raise your top arm and leg as high as you can to form a star shape. Start with one hand and one foot on the floor. One of the hardest isometric holds, the side plank star requires your core to keep your body not only straight but also stable, as you raise one leg and one arm. At this point make the move harder by resting your elbow, or even both feet, on a gym ball. Then gradually increase the duration to a minute. Start by doing 15 seconds on each side, so each side plank set lasts 30 seconds. Raise your hips and engage your abs – imagine drawing your bellybutton in towards your spine – and hold this position without any hip sag. Start on your side, with your weight on one elbow and legs together. Side planks place a greater workload on your obliques (side abs), as well as the deeper-lying muscles of your core.

Muscles targeted: Glutes, hamstrings, quads You can use these as workout finishers or do them as a circuit, cycling through three rounds of holding each position for 20 to 30 seconds. We asked Marvin Burton, head of fitness at Anytime Fitness, for his favourite isometric exercises. Regular isometric training will increase your strength and core stability, and there are mental benefits to it as well, because it takes a lot of willpower to hold a challenging position for long periods while your muscles scream at you to let it go. Then the shaking starts, the burning feeling in your muscles begins to grow, and you rightly admonish yourself for ever doubting the potency of isometric exercises. To the uninitiated, simply holding a position like the plank can look pretty easy as well, and in the first few seconds of performing an isometric exercise you might start to wonder if it’s doing you any good at all. When someone performs an isometric exercise in a busy gym it looks very out of place – an island of stillness in a sea of people powering through HIIT sessions or chucking heavy weights around.
