I recommend my clients perform a series of preparatory movements before training, including these isometrics to "activate" the core muscles. By performing a series of static core exercises such as the plank, side plank, bridge, and lying back extensions, you can engage the midsection and prepare it for the workout ahead.
You only need to hold each position for about 15 seconds... not long enough to fatigue it, but enough to get those muscles firing. Watch my video demo "here" for a thorough explanation.
