END GOAL ?
The End Goal DETERMINES the type of specific Training and what
'MIX' of energy systems are required to best
ACHIEVE THE END GOAL 
Best to start with the END GOAL IN MIND and Work Back from there 
Cycling and Periodizing your Specific training plan to achieve those GOALS 
Of Course we Advise you not to MIX your "Cardio and weights" training as "Different energy systems" are involved for BEST RESULTS (see diagram above)
THE "HORSES for COURSES" Theory always wins out at the 
END OF THE DAY 

All Sorts of RIDICULOUS TRAINING STUPIDITY IS PRACTICED TODAY 
without any thought for the "END GOAL" or "PURPOSE" "FUNCTIONAL TRAINING" must by defination have
"A FUNCTION or END GOAL"
ask yourself that simple question before you INJURE YOURSELF doing stupid things designed by equally stupid people with litte or no experience or understanding of the body's biomechanics or energy systems.
