I stumbled accross an article by legendary John Berardi on his website about how he trains his ‘sprint athletes’… a mixture of weights 3 x per week (push/pull/legs) and HIIT cardio (3 x per week) like so:
Day 1 - Weights (Upper Body - Pushing Type Exercises)
Day 2 - Anaerobic Interval Training (Rowing)
Day 3 - Weights (Lower Body)
Day 4 - Anaerobic Interval Training (Cycling)
Day 5 - Weights (Upper Body - Pulling Type Execises)
Day 6 - Anaerobic Interval Training (Running)
Day 7 - Rest
If I made it 45 minute weight sessions and 20 minute HIIT sessions (with a brief warmup and cool down), do you think this would horribly overtrain me? JB says it links in to his ideas of G-flux, whereby whatever your goals, the higher levels of energy expenditure and intake you’re at, the better your physique will be. He also says this type of training is aimed at developing the kind of lean, muscular, athletic, sprinters physique.
