✅ CHALLENGE ACCEPTED! ✅ The assualt bike, or in this case echo bike challenge is one of our favorite benchmarks to.... watch.... 😜😂 It will have you crawling on the floor for 30 minutes after you finish! ​ ​Challenge: How many calories can you get in a 60 second all-out sprint on the bike? ​ ​✅ This is absolutely a max effort challenge, do not phone it in! ​✅ The first 30 seconds won't seem so bad, you'll build up some confidence as you watch the calorie counter rise ​✅ Soon after you cross the 30 second mark is where it starts to get tough and you'll start thinking of quitting. Do NOT slow down! ​✅ The last 10 seconds feels like 10 days! Don't watch the clock, keep going! ​✅ Pro Tip: It helps to have someone yelling at you the whole time 😂 ​ ​Have you done this challenge before?
