The 1/2 Hour Workout

time challenged?  granted an hour workout is preferable but if you only have a 1/2 hour, maybe during your lunch break or right before or after work, are there any real benefits? yes! but  in  part that depends on you and/or your trainer. you need to be disciplined enough to do it and you both need to know what type of movements to do for the most benefit.
for example-2 groups of people each did a 1/2 hour of movement. the first  group biked on a stationary bike for 30 minutes. the second group biked for 15 minutes then did 15 minutes of weight training. after 8 weeks the first group lost 3 1/2 pounds, the second lost 8 pounds. besides the benefit of greater weight loss the second group had the additional benefit of losing a greater percentage of body fat while gaining a greater percentage of muscle or lean body mass. most of us need and want more lean body mass to make us healthier, stronger and able to burn more calories- even when we are not working out.
so if you are not working out because you only have 30 minutes- think again the benefits are worth it.
