As the high-intensity workout vs low-intensity workout increases in intensity, research suggests that cranking things up, even for very short time periods, pays off big time. The Los Angeles Times reports on two studies published in the Journal of Physiology showing that working under maximum capacity for short bouts, interspersed with
stints at a lower intensity, may produce physical improvements without
having to spend hours exercising. One study put seven men in six stationary cycling training sessions consisting of eight to 12 one-minute bouts of
high-intensity exercise alternated with 75 seconds of recovery. In all,
sessions lasted about 20 to 25 minutes. Over two weeks the participants
did two hours and 25 minutes of exercise. Another study required participants to exercise at maximal capacity for short bouts on specially
designed stationary bikes or did more moderate cycling for much longer
periods. In that study, both groups showed similar improvements in
exercise performance and muscle health. Both studies showed improvements despite the fact
that the high-intensity bouts were done below maximum capacity and on
standard stationary bikes.
For maximum work out I would not go for just any stationary bikes but I would go for the upright stationary bikes which moves more muscle than a recumbent stationary bike. They may be expensive when buying brand new but there’s this guide that I saw about used stationary bikes it may be of help 😉
