Hi all! In the quest to get the most benefit in the least amount of time, I came across something called REHIT (Reduced Exertion HIIT), which is a variation of Sprint Interval Training (SIT), which is a variation of High Intensity Interval Training (HIIT)... sorry for the acronyms lol...
The key finding is that this workout is only around 10 minutes long and consists of just a total of 40 seconds of sprints. The REHIT protocol is this:
Total time: ~10 minutes
- Warm-up (3-5 mins)
- Maximal intensity sprint (20 seconds)
- Complete rest (2-5 minutes) - complete meaning that you rest enough to be able to do another MAX intensity sprint at the same performance as the first
- Second Maximal intensity sprint (20 seconds)
Here's a link to the two main articles I found researching this:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6763680/
https://pubmed.ncbi.nlm.nih.gov/28079707/
The second article even found (through a meta-analysis of 34 studies) that increasing the number of sprints might even reduce the benefit on aerobic capacity (VO2Max).
Have any of you looked into this or have tried it? I'm just curious what results people might have had.
I'm just starting out my journey but am going to try this and see what happens. I've made a couple of YouTube videos on the subject (that I won't link to so as to not self-promote), but it definitely sounds interesting.
Anything where I can do less work is interesting lol
