High-Intensity Interval Training (HIIT) Timer

-
Typically, an interval timer may costs anywhere from $15 to $100+.  Now, interval timers are free as long as you have a smart phone.  There are a lot of interval timer apps on the android market, but many of them either have an obnoxious alarm or fail to alarm if the work and rest intervals are set to 3 and two seconds, respectively.  Short intervals are important for targeting eccentric or concentric muscle contractions to produce the appropriate training effect.  I was surprised to find that this timer could function even if the interval was set to the shortest possible duration (1s work/ 1s rest).

To get the same app, search "hiit interval training timer" on the android market and download the app with the square icon, silhouette of a runner and the letters "HIIT" underneath the trailing leg of the runner.

PROS:
  • It's free!
  • Easy to use
  • No obnoxious alarm at the end of each timer
  • Loud enough to hear outdoors while running or cycling
  • App can operate in the background
CONS:
  • App interface could look better... can't really complain since it's free!

Caleb Ewan's Sprint Position - Revealed through Kinesiology

Caleb Ewan has been disrupting the sprint scene with a "new" sprinting technique that combines the aerodynamic benefits of a super tuck with a modified pedal stroke. Below is a still grabbed from the video (at end of post): Sprinting in a low position isn't new; in fact, some of the riders that followed (off screen) were in a lower position than Caleb Ewan. What's different is that whenever he assumes this position, the six O'clock position of his pedal stroke shifts backwards to seven O' clock. This only happens if he primarily uses hip extension (gluteal muscles) to move the pedals. Being able to continue using the strongest muscles of the body in an extremely aero position is the secret to his success. WHY THE 7 O'CLOCK SPRINT TECHNIQUE IS THE FASTEST There are two things that matter in a sprint: 1. Power 2. Mass Sprinters have the problem of having more power than mass. When you have more power than mass, the power you send to the pedals will also

Eagle Creek Park Cycling Grand Prix v2.0 - FIRST PLACE & FIRST PODIUM FINISH!

I can't even begin to describe how awesome it felt to have two dreams come true at once!  I always wondered what it would be like to be on the podium, but I never thought I had a chance at first place! THE COURSE Below is a map of the course highlighted in blue.  It ran counterclockwise.  There were a few corners that stuck out to me. Bottom right (corner #1):   This wasn't a very sharp corner, but the trees and brush made it difficult to see around it, so the group had a tendency to slow down and merge into a single line here. Top right (corner #2):  This corner was very sharp, so oftentimes the group would merge into one or two pacelines, especially at higher speeds. Top left (corner #3):   The inside half of this corner was covered by loose asphalt, so it wasn't an ideal or safe place to pass.  Pretty much everyone had to take a very awkward, wide line.  We could only fit about three abreast in this corner. Bottom left (corner #4):  This was a very fast co

How To Hold an Aero Position

The worst thing a rider could do is force a low aero position and hope for the best.   With low back pain being one of the most frequent complaints among pros and recreational cyclist alike, the chances of
