Hi,

I just starting to replace my former cardio (LISS - 1 hour of stationnary bike or rower) by HIIT.
The problem is that I start slowly, with 5 min session (that I'll increase when I feel comfortable). So I don't really feel like going to the gym for just 5 min !! :confused:

I think that I could do the cardio right after the lifting.
20 mins warm up, 40 mins lifting, then 5 min HIIT.

Does it make sense ? (I'm cutting)

As it's suggested to eat right after lifting and not to eat during 1 hour after HIIT, it seems that HIIT and Lifting in a same training is not compatible. Right or wrong ?

In case I can do both lift and hiit, what should I eat before and after workout ?
Today, I eat:

Before Workout (meal 2): 100gr tuna, 1 egg, 1 whole wheat bread slice

After workout (meal 3): chicken breast + veggies (spinash, green beans)

Also, I lift 4 times a week. Shall I do HIIT with all liftings ?

Thanks for you help!!

Doing more cardio isnt a bad thing. So yeah I suggest u do it on workout days I do 10min HIIT on workout days and 20min on Offdays.

Only thing i can think of why u dont is lack of energy or bad knees.

I personally wouldn't do HIIT and weight training in the same session. At the minute it might be okay if you're doing just 5 minutes, but when you get up to 20+ minutes, you'll struggle to get an effective workout for both cardio and HIIT, since ideally both should be pushing you to your limits.

Ideally for hitting the weights, you want to be full of energy... NOT how you feel after a HIIT workout. The same goes vice versa.

If your schedule allows it, keep cardio and weight training separate for the best results (you'll be able to get an effective workout every time, instead of lackluster HIIT/weight training because you're drained of energy).

If not, I'd keep the LISS.

Well, there's the 4-5 minute warm-up and cooldown, so that should bring you to close to 15 minutes. And if you're doing 5 minutes of intervals are you doing.... three one-minute-long ints? If that's killing you, you could do what I'm doing and do more ints at a slightly lower time... I do 5-7 45 second ints with 1-1:15 "rests". I'll move up to fve 1-minute long ints in a week or two.

As for doing them after weights, I'm no expert, nor am I very experienced, but I've done them just fine after weights... Though what I'm doing now is 45 mins MISS on weight days and HIIT on off days.

I did HIIT today after weight training..no problem.

I have found that there are not a lot of things that are not "ok to do" if nutrition is correct.

Thanks you guys for the answers!

What I do is set the bike's computer to "Intervals", which define a non-configurable "hill" profile, consisting of 6 "hi" and 7 "low" (1 low at start, 1 low at end).
That makes really short periods (20 secs), but when I increase the time, the periods will stretch.
The problem is that rest periods last as long as hi periods.
I don't have much time to warmup also (just 1 period), but as I do it after workout, I'm already warmed up.
I will go on like these, as I feel that I have enough energy left to do this after lifting (maybe I should lift harder :bb:), and I will advise when the periods get longer.

Thanks again!

You could do HIIT after weight training, but the fact is if you're pushing yourself in weight training and working hard, you really won't have much left for HIIT. I'm NOT saying if you can do HIIT after weight training you're not working hard, but after lifting for me, I'm usually pretty spent and trying to do HIIT after lifting in my case would not only be difficult, but probably a lackluster performance. Try it and see what works best for you, everyone's different.

I don't think he meant you shouldn't do it because it's not good for fat loss. I think he meant that if you have enough energy for a 20+ minute HIIT workout after a lifting workout (notice he specifically says a few minutes is OK), you're either in superb physical shape or you don't lift and/or do HIIT with maximal effort.

To the OP: If you were doing an hour of LISS, you should most definitely be fine with more than 5 mins of HIIT. Start with 90s walk/30s sprint. Do this for 10-14 mins after a 5 min warm up and then add a 5 min cool down. That, coupled with 10-15 minutes of stretching after gives you more than enough reason to hit the gym. Don't be afraid to do jump right into HIIT if you're in fairly good shape. If need be, just don't go "all out" for the first couple weeks until you build up to it.
