Holy hell…I’d forgotten how hard these are.
Tried 6 x 3 min. Got through the first 4 starting around 120%+…petering out to around 110-115% by the end of the interval. The 5th…man I was down right at threshold 30 seconds in and fighting for dear life, didnt even attempt the last one lol.
I guess my question is…if the best I can do is hang around threshold for the last half of some intervals, with heart rate still pegged at 180+, is it still worth continuing? Of course Ideally I suppose I’d starting hitting these a bit more consistently a few weeks down the line…but still curious.
