Har gjort noen søk, men finner ikke noe som sier at man mister muskler ved å kjøre GK om morgenen før frokost... men jeg fant denne:
High intensity interval training is relatively simple to perform but does require a good level of motivation.
To perform a HIIT session, I recommend you use cycles of about 4 mins, with each cycle consisting of a maximum effort or sprint for 20-30 seconds followed by a 3 & a 1/2 minute power walk at about 50-60% effort, each session in total should last from 20 to 40 minutes depending upon the individual.
The session can be adapted to be performed on any any piece of cardio equipment at the gym or if you are an outdoors person I recommend that you run on an athletic track or grass if possible, to avoid chronic stress to your knees and ankles.
If you do run on the road another good idea is to use telegraph poles to pace yourself, by running from one to the next and then walking for 3-4. Just like with any form of cardiovascular activity it is important that you build up the intensity and duration of your HIIT sessions gradually to avoid undue fatigue or injury. Over the course of an 8 week period try to run about 200m further than the total distance but, in the same time as when you first started, once you feel comfortable try adding on another cycle.
To gain the most benefit out of this program try to complete on an empty stomach such as in the morning before breakfast. Also use this cardiovascular workout in conjunction with a balanced diet and the correct supplementation.
Og jeg finner flere som kjører som kjører GK/HIIT før frokost, gjerne etterfulgt av magetrening. Fikk også opp treff hvor dette var anbefalt i "Body for life"-programmet... Jeg skal nå uansett fullføre min MGK før frokost minimum 3 ganger i uka i 8 uker, for å se hvordan dette fungerer. Til nå så har jeg økt muskelmasse... MEN, jeg kan tenke meg at hvis jeg oppnår en fettprosent på ca. 10%, og fortsetter med MGK, så kan det nok hende at den energien som kreves blir hentet fra andre kilder enn overflødig fett....
