Lately energy system work has caught my attention. I've been reading running man and saw alot that speaks to me.
I've also been reading Joel Jamieson, as far as I understood quite a knowledgable man in the conditioning realm, and he got me quite crossed.(Is that from a song?)
Because you're an expert on most things training related, you seemed to be the right person to ask.
His protocols seem so easy. This is a summary of what he told on Breaking Muscle:
Anaerobic Lactic system: 30-40 s. work, 1-4 minutes rest, 2-5 sets, 1-2 series
Anaerobic Alactic system: 3-6 s. work, 60-120 s. rest,10-20 sets,explosive work
Aerobic system:method 1:HR 130-150, 30-90 minutes
method 2:8-10 s. work, 60 s rest,8-16 sets, moderate intensity
method 3:5-6 s. work,60 s rest,mod./high volume,high resistance
Do you feel this kind of protocols will be effective, or should conditioning be harder? This kind of ease makes me sceptic.
