Hiit vs Running which is better

It is the impact that causes the wear, not the muscle activation. More steps means more individual impacts. Probably more of an issue for people that are overweight, but still.

But sprinting is harder impacts

Yes.
Millions of people do it every day.
It works
It doesn't raise your appetite, the impact on your joints is minimal and it's gentle enough that everyone can do it.

Box jumps are a retarded way of accelerating wear on your knees

The answer is HIIT is better, if OP is describing what is going on in pic

The difference is plyometrics in HIIT.

Protip: you can apply plyometrics to running- its called "skipping"

Dont be afraid to look like a retard tho

>Box jumps are a retarded way of accelerating wear on your knees

Depends entirely on form.

Practicing it in a class (following a generic routine, generic box height, etc) is much worse in that respect than individual, focused on form, customized for height, reps and length

Minute for minute, plyometrics is probably the best possible full body workout you can do

Sprinting involves much more forward momentum and is focused on the forefoot which absorbs the shock more readily. Running should look like this too, but most ssc is similar to jogging, which has more of a vertical bouncing motion, which causes the wear.
A source that suggest as much:

I recall hearing the same in an athlean vid as well.

>which is better
Depends on your goals. You'll have to be more specific. Also just wanna say some people do 40 or more seconds of "high effort" during intervals, which is completely ludicrous. During HIIT you don't do "high effort", you do MAXIMUM effort for 15-20 seconds. If you do more than 20 seconds, you're not pushing yourself enough.

Yep, you absolutely can lose weight by walking. The caveat is the rate is slower than alternatives like HIIT, but it's definitely significantly better than nothing.

>However Running will get you a better cardiovascular system overall.
What does this mean?

>Bodybuilding:
>Walking and lifting
Isn't HIIT also acceptable to do with hypertrophy routines as long as it's not on the same day as the lifts?

The distinction between running and jogging is important

95% of the people I see running around my town have absolutely terrible form... not only are they damaging themselves they aren't in good shape to begin with.

In the gym on treadmills, form was only marginally better

Monitor your heart rate. Sprint until it gets real fucking high. Start walking until it gets really low. Sprint again until it gets real fucking high. Stop at some point rehydrate and repeat in the future. Congratulations on getting in absurd cardiovascular shape.

LISS suggestions for boxing/mma?

this is basically caveman hiit. for the most part it's sound advice but there's no real point in monitoring your heart rate if the ranges are nebulous like "really high" and "really low". make sure your heart rate gets above 90% MHR and try to sprint all out for 20 seconds. then walk until your heartrate gets to maybe 60% or 65 MHR.

also it's important to warm up and cool down before doing hiit with like 5 minutes of ~65% MHR.

i blame nike for putting 3 inches of foam into their running shoes.

Eh, you can put them in on the same day. Just lift in the morning and do HIIT / metcon / AMRAP / whatever interval work in the afternoon. Even doing something like an assault bike / airdyne tabata as a finisher to your strength training sessions is fine. Just eat a lot and don't do low carb fad diets. Most of the guys I work with including me do something like this 5-6 days / week and we all manage to pull our own against people that specialize in this stuff while still having the energy to practice our actual job skills:

Actual Work (works anaerobic capacity mostly)
Strength Training
MMA drills
Rock wall break
Metcon / interval work
Ruck / LSS
