are so many ways to strengthen and tone the muscles in your core area, as well
as, challenge their endurance for maximum calorie-burn and optimal results.
if you’re in a rush that day, you can still execute a single move at maximum
effort to achieve results. The key is to know which exercises are most
productive for you.
take the Russian Twist for example. Watch the video here and review the correct
way to execute this exercise. Then, depending on your fitness level, if you’re
more advance, you can perform 100 repetitions and repeat it 2-3 times. If not,
one set of 100 is a good place to work towards.
fitness level you are, do not rush through this exercise. Take your time and
fully challenge your core by executing in an even pace, and fully engaging your
ab muscles throughout the entire workout. No swinging, no relying on momentum,
no cheating!

note: If you have a bad back, a stiff back, or a weak back, you will feel
discomfort in your back while executing this exercise. If that is the case, do
not proceed with this exercise. Instead, tend to your back issues first by
doing back strengthening exercises, specific ab exercises, and overall body
stretches, especially in the core area. Even a massage will help. Then, when
you’re ready, you can come back and try this exercise again.
