Small, But Very Useful, Change To Exercise

If feeling tired, it is still a good idea to do 2 minutes warm-up before doing the stair exercise (2 minutes at gentle pace, 1 minute at intensive pace). However - I just tried doing 1 minute warm up and 1 minute intensive, and it worked very well! It saves time, and is much less boring! From this tiny, non-scientific experiment, it seems that intensive exercise is best done as a quick warm up followed by quick action - the benefit coming as both saved time and increased excitement!
