At what point do you know you're pushing yourself to far? I play DDR on heavy mode, while this may seem silly or dumb it can be very physically stressing but its not uncommon for friends to push themselves playing on and off for hours a day or until there legs turn to jello.
This is much like HIIT in the sense that it requires 1:30 bursts of energy per song, usually you do one or two extremely stamina draining songs with one easy song in between.
Still, my stamina nowhere reaches some of my friends (although I am much more fit after playing for 5 months in the arcade) I do want to give my stamina a boost but also don't want to overdo what I am doing especially since I'm moving back to Maine so my access to the machines will be an almost daily thing. I was debating doing renegade rope training to get my stamina/agility up(to be able to do the hardest songs on the game, 10 footers - which I cant do yet.
To give you an example 10 footers have over 1000 steps/jumps in about a minute to 1:30 time period I can only get about 1/2 way through the 10s before my body tires to much) but then I got a thought that I could be over exerting my body already when I play DDR for extended periods of time.
If you feel the need to lecture me please do so. I would like to know if what Im doing or want to do is unhealthy.
