Intermediate to advanced level fitness.  However, anyone can try them and scale the sets/reps as needed, or modify specific exercises you are not able to do, and slowly work up to the full amount.

These workouts are gym based, so you will need gym access to be able to perform all of the exercises.

The program is broken down into 5 days a week.  I always suggest to train 2 to 3 days, then take at least 1 rest day.  Training 5 days in a row will not allow you to recover as much as needed, and you may experience much more fatigue and breakdown by day 4 and 5.  You can shift the days around as needed to best suit your schedule, and if you cannot commit to 5 a week, do as many as you can in a rolling fashion.  For example, if you can do 3 a week, schedule out the first 3 in week 1, then the next 2 in week 2 and restart with day 1 as your third workout for that week.  You will be cycling through these 5 workouts 4 times, so how you schedule them out is up to you and what suits your schedule best.

To get the best outcome from this program, I would encourage you to stay as consistent as you can with the structure of the workouts themselves.  Try to improve your movement patterns and mechanics, and overall strength and aerobic capacity.  You should notice that you have a much easier time getting through each workout in week 4, then you may have had in week 1.

The goal of the this program is to help you increase both your strength and conditioning, as well as provide more variety and fun ways to challenge yourself.
