These types of exercise are from movements where the muscle length stays the same whilst a load is applied. Isotonic exercises are where the muscle shortens and lengthens to create movement against a load. This core routine involves both. You'll see that at the start I take my arms overhead with my head down whilst focusing on keeping my ribs in -therefore my abdominals stay the same length whilst my ribs are desperate to pop with the weight of the ball (which is 8kg). When I add the abdominal curl I am shortening my abdominals (isotonic). When I add in the hold at the top and move the ball again I am back in an isometric exercise as I try to keep my abdominals short against the weight of the ball. Combining these 2 types of exercise helps to create not only strength but endurance. Endurance is so important when you think of how long we are awake and how long our bodies have to work for each day. Give this a go but please put technique before reps!! No popping ribs, no arching your lower back, no hunching at the top. Enjoy 💪🏼 #athleticsnotaesthetics #strongnotskinny #themodelmethod
