First: There is no substitute for the power clean
for a younger guy. You don't need to do them, so there doesn't have to be a substitute. Just deadlift every session -- which at your age should be twice a week -- and go up every workout.
OK--that explains it perfectly.
Second: I don't personally like the C2, because I don't like stationary cardio -- I haven't figured out a way to read on a C2. The C2 is as good a cardio device as is available, after the prowler. If you want to use a C2, fine with me.
Understood. Followup Question: IF I had a prowler and a place to push it--what is your opinion of an old fart using these devices from hell?
Also: I think you do the C2 on one other day per week. No more is necessary, as you will discover when your squats get heavy enough.
Any recommendations as to C2 Warmup/Work Intervals/Rest Intervals? for HIIT.
Finally:
Conditioning does not provide bodyfat loss, especially at the volume you'll be able to tolerate. For you, bodyfat loss will be a function of diet and muscle mass growth. That's it. Tighten up your diet, and you'll lose some belly.
