I started BBS in October working out every 7 to 9 days. I normaly do my push ups to warm up before starting. I think this is one of the best thing i have done for myself last year. I work out a few times with my two teenage boys.They also echo the same sentiments. I have reduced my morning walk from two days per week to one. I have almost discontinued my weekly yoga practice.Yoga practice was done 2 or 3 times per week.i hope to incorporate yoga at least once per week to achieve a good balance.
