Turbo Trainer Advice

It's just a very static activity.

Ideas:

• stand up/shift position occasionally.
  
• limit sessions to 45mins (worth about 1.5hrs on the road)
  
• raise front wheel (I use about 2 to 3 inches worth of phone directories/catalogues)
  
• consciously slide back a bit, to make sure your sit-bones are on the widest part of the saddle.
  
  

You can get a lot of benefit from 5 to 10 mins warm-up / 5 mins warm down / 20 to 30 mins actual 'work'.

Billions of sessions posted on the interweb, geared to different needs ie. spin/form/strength/power/VO2/lactate threshold/recovery/blah.

I'm assuming you've got a towel draped over your top tube and a great big fuck-off fan pointing at your face :D
