WHENEVER you work out, you’re told to “keep the core tight.” What does that mean?
“It’s about strengthening your core so it can hold up your body during fitness training or a competition,” said Jerry Diaz, a National Academy of Sports Medicine certified personal trainer.
Core exercises are an important element of building a balanced fitness program, he added.
Core exercises stimulate the muscles around the lower back, pelvis, hips and abdomen so they can work together, Diaz said.
He recommends a series of mat and upright core dynamic movements. These include roll ups, plank variations, back raises, v-twist, and toe reaches.
Standing exercises include stationary lunge rotation, step back overhead reach, rotation reach, single leg balance, single leg balance multi-direction, and squat to overhead reach.
Diaz said fitness training that includes core training can improve your balance and stability.
But, he added, always consult your doctor before starting an exercise program.
