The Now What Fitness Series lays out the foundation of fitness in a concise and simplified manner, making for a collection of books that help the reader truly comprehend how to improve one's health and well-being from A to Z. I've broken fitness down into comprehensive concepts, giving anybody who truly wants to change their health and their lives in profound ways, the step-by-step tools and knowledge to do so. 


The American College of Sports Medicine (ACSM) has instituted a list of cardiovascular fitness guidelines, which I have listed for you below. 

  • The 3 basic components to any exercise conditioning session are warm-up, conditioning stimulus, & cool-down.
  • Warm-up & cool-down performed at approximately 50% of stimulus intensity (hold conversation without much difficulty).
  • Warm-up & cool-down may take 5-15 minutes, depending on age & fitness level.
  • Accumulate moderate-intensity exercise (40-60% of HRR) for at least 30 minutes on 5 or more days a week, for a total of 150 minutes per week, or vigorous-intensity exercise (60-85% of HRR) for at least 20-25 minutes on 3 or more days a week for a total of 75 minutes per week. For weight loss, 50-60 minutes per day to a total of 300 minutes moderate exercise is recommended. (Intermittent activities in 10-minute increments have same health benefits as continuous activities.) *See "Intensity" below for explanation of HRR.
  • Frequency: At least 3-5 days a week.
  • Intensity: 40-60% of (HRR) heart rate reserve is considered moderate intensity and 60-85% heart rate reserve is considered vigorous. Very deconditioned individuals may begin to improve at about 30-40% of HRR. To figure your estimated HRR use this equation: 220 – age - resting heart rate x .60 to .85 + resting heart rate. For more on that check out the Target Heart Rate page.
  • Duration: 20-60 or more minutes per session, continuous or intermittent activity. If you are very de-conditioned you may even need to split it up into several 10-minute segments. Like Nike says, JUST DO IT! Increase your duration by 5 minutes a week until you reach your desired amount.
  • Type: Aerobic (run, brisk walk, swim, cross-country ski, dance, elliptical trainer, cycling, stationary bike, etc.)
  • The 3 stages of cardiorespiratory training: Initial, Improvement, Maintenance.
  • Progression of both intensity and duration in a single session is not recommended. Increase the duration first before increasing the intensity. If you can complete an exercise session at the upper level of frequency and duration for 2 weeks without signs of excessive fatigue, progress to the next level.
  • If training is discontinued, gains in fitness regress by approximately 50% within 4-12 weeks.
  • If weight loss is your goal, frequent, enjoyable exercise periods of low to moderate intensity and relatively long duration result in the largest weekly caloric expenditures.
  • Stay within your heart rate range. Monitor through a heart rate monitor or manually at carotid artery on neck or radial artery on thumb side of wrist.
