Ham Sandwich features sweet spot over/unders, with 30/30s "sandwiched" in between. The over/under intervals are alternate between 2 min @88% FTP and 30 secs @110% FTP. The 30/30s up the ante a bit and alternate between 30 secs @130% FTP and 30 secs @50% FTP. Yes, there are rest breaks, but they are purposely short to keep the heart rate and metabolic demands up. Better eat your sandwich quick before the bread gets soggy...

Sustaining high levels of lactate requires specific training. This ability to tolerate lactate only comes with precise intervals in training. We can all produce a one off effort to build lactate, but with carefully planned intervals we can maintain this high level of lactate for an extended period. This is where the training effect happens!
