Answer: One great way to avoid a plateau is to simply increase your current exercises’ difficulty. This allows you to keep the same general program but has you modifying the exercises themselves. One option to increase difficulty is to reduce the weight being used while increasing the reps being performed (or vice versa).
Another option is to consider incorporating stability-challenging equipment, such as stability balls or suspension cables. The plank, as an example, can be performed using either piece of equipment and will force your body – particularly your core – to work much harder given the ‘instability’ of the equipment being used. In order to use new pieces of equipment properly and safely, it is important that you know how to properly activate your core so be sure to speak with your trainer before incorporating stability-challenging equipment into your workout!
