If competitive cycling isn’t your thing, but you just want to take your fitness to the next level, then this is the workout for you. Our bodies constantly adapt to the stresses (workouts) we expose them to, and in order to prevent plateaus, we need to incorporate a little variety every once in awhile to shake things up a bit.
In this workout, you’ll complete a series of 4-minute intervals, all with a different focus. Whether it’s increasing the resistance or bumping up the speed, each interval is a major calorie burner. Allow your body to recover as much as possible between rounds, but get ready to work during the difficult 4-minute intervals.
The resistance will steadily increase in your first 4-minute interval. The goal here is to find a
comfortable RPM, ideally between 70 and 85 revolutions per minute. Once you’ve settled into a comfortable cadence, you’ll steadily increase the resistance, trying to keep your RPMs as steady as possible over the whole 4-minute interval.
Your second 4-minute interval will steadily increase RPMs. You’ll start at a slow to moderate cadence and without adjusting the resistance, you’ll gradually increase your cadence every 30 seconds. Be sure to not start out too fast, or set the resistance too high. Both sets will probably feel pretty easy at the beginning, but should become very challenging during the last minute or so.
Well, what are you waiting for? Let’s get to it!

How to Bring Your A-Game to the Train for a Tour Series (Part 1/3)
If you’re familiar with the cycling world and follow European racing, you may have come across both myself and the team I coach, the UAE Team Emirates. I’m Kevin Poulton and have coached for nearly 25 years, specializing in Spring Classics riders and sprinters. In that time, I’ve been fortunate to coach elite World Tour professionals and work with some of the best teams in the sport. My athletes have secured victories in Paris-Roubaix, Tour de France stage wins, World Championship Road Race podiums, and multiple Spring Classics podiums. And now, you’re my next athlete! The Series Structure I designed the Train for a Tour Series much like the programs I use at UAE Team Emirates’ training camps. Over six weeks, your iFIT Trainers (all of which are pro cyclists themselves) will run you through an immersive World Tour pre-season experience. You’ll train in Mallorca, Spain, as it is the ultimate training destination for professionals. Every winter, World Tour teams flock to the island for their pre-season camps, and for good reason. The terrain is incredibly diverse, offering long, steady climbs, rolling hills, and flat coastal roads—exactly what’s needed to develop all aspects of cycling fitness. The Train for a Tour Series gradually builds in intensity, taking you from controlled endurance efforts to high-powered, race-specific efforts. The workouts follow a carefully structured progression: Early Weeks: Lower-intensity, steady-state efforts with proper recovery, laying the foundation for improved aerobic endurance and efficiency.Mid-Series: More focused interval work, targeting different energy systems, including fast-twitch muscle activation, anaerobic power, and high-intensity efforts.Final Weeks: Race-like sessions, including VO2 max intervals, lactate tolerance efforts, and short recoveries, mimicking the demands of competition. If you follow my training program as I’ve laid out (and you ensure that the SmartAdjust™ feature on your bike is on), you can expect to see improvements in your cycling performance, endurance, and ability to sustain high-intensity efforts.
