And before asking if HIT is right for you - Search the Darden forum for basic HIT routines and/or simple advice. Maybe try a routine at least once - and then return here with any questions.
If you like strict/controlled/slower reps, prolonged sets up to 90 secs, supersets, short rest periods and few sets per musclegroup - You may like HIT! But, few HIT people train more often than 3 times a week.
As many may already have said, I recommend you choose a direction/program to follow for at least a month to evaluate. In my opinion, results from training rely upon sticking to a routine over time - to be able to measure your progress.
