user: How to get an efficient cardio workout and improve your speed, and gain other health benefits?

assistant: In this day and age when many are busy with work, family, electronic gadgets, social media it becomes increasingly challenging to find the time to exercise.  Staying healthy will allow you to enjoy those distractions longer, but jokes aside it will make you feel energized, motivated and bring out the best in you.  When new discoveries in scenic areas are correctly applied, you don’t need to spend multiple hours at the gym, you don’t have to starve to achieve your goals, this concept was very enticing to me when I first learnt about the Sprint 8 program at my local gym.  I decided to give this a try!

Sprint 8 - Its a 20 minute routine, where you spend the first 30 seconds working out at the highest level of intensity (go all out) followed by 90 seconds of active recovery, repeat this 8 times..  You can use a bike, treadmill, elliptical whichever suits your style.  In all my life of being fairly active, Sprint 8 has the toughest workout, but over a year I could see significant results.  I was able to run faster, lower blood pressure, reduce fat percentage, and improve muscle mass.  The key differentiator about this program is that it engages all the three muscle fiber types and releases exercise induced growth hormones to help your body become stronger, leaner and healthier.

Another advantage is that this program really reduces any change of injury that one may face by running, heavy weight lifting etc therefore allowing you to sustain the exercise program for years to come.  

Give this a try and gain the benefits of efficient exercising.

user: How long should a child's carseat remain rear facing?

assistant: Extended rear facing until the child reaches the maximum height or weight limits of the carseat is the safest option. When a child is sitting forward facing in a frontal collision a large amount of force is exerted onto the head, neck and shoulders leading to serious injury like paralysis or death. If the child is sitting rear facing during a collision, the force is spread over a greater area of the body with less pressure on the neck, head, and inner organs. Children should sit rear facing as long as possible, in case of collision it reduces the risk of serious injury or death by more than 90%. You should consult your car seat's manual to determine the maximum height and weight restrictions.
