Schedules are tight in the morning but you can get a good workout in only ten minutes a day. What maximizes time and works really well is using an exercise routine that splits the body into major muscle groups, exercises one or two muscle groups per day. What really condenses time is doing each exercise slowly about 8 seconds per movement. For instance 8 counts on the lift and 8 counts on the lowering phase of each movement. Each exercise should be performed 8-12 reps. You need to use enough weight so you can barely perform the last rep.This gives the muscle group enough of a workout to only be done once a week. Can use own body weight, hand weights, cans, or resistance bands.
