Just completed a lovely Sunday morning Spring sprint interval session. 30 seconds of hard sprinting followed by a 90 second walk. After completing 15 cycles of this I’m feeling a bit fatigued (just a tad!).
Intensity is where it’s at! By the last 5 cycles I was up to 96% max heart rate (185 bpm)!
Anybody else out there kicking their own ass with the sprints? If you’re not, give it a go as you be pleased with the excessive calorie expenditure.
By far one of the most challenging cardio sessions you will ever do!
