Review//Endurance Booster

[Selkie]

Endurance Booster is one of the new Spinverval releases and it's intended to be a high aerobic workout.

Duration: about an hour and 46 minutes

Overall, I enjoyed this one and found it challenging. It definitely lives up to its promise (endurance boosting). Not as fun as Hillacious, it isn't deadly boring either. The sets go as follows:

• Typical Spinervals Warm Up Set
• 15 minutes, switching gears every so often. This is more or less a pyramid set, starting at BCR 15, gearing down to BCR 17 then back up to BCR 15 at the end.
• 15 x 1 minute, alternating BCR 13 (1 min) 15 sec rest, BCR 17 (1 min) with 15 sec rest, repeat.
• 10 x 90 seconds, alterating BCR 13 (90 sec) 20 secs rest, BCR 17 (90 sec) 20 seconds rest, repeat
• 7 x 2 minutes, alternating BCR 13 (2min) 30 sec rest, BCR 17 (2 min) 30 seconds, repeat
• 15 minute set to finish, moving between BCR 15 and BCR 17 (not really a pyramid and more standing in this set, thank goodness).

DVD quality is good and the time, effort, gear ratio lists at the bottom are easy to read. Coach Troy music volume is very low which isn't a negative, and to be honest, I ignored it. He talks a good bit, as usual. This one was filmed at a gym and there are a bunch of cyclists who range from obvious triathlete to "the rest of us." I liked that there were people of all sizes, ages, etc.

This is a good workout for longer sessions and endurance junkies. It definitely is a welcome addition to my Spinervals library.
