In Total Body Workout instructor and exercise physiologist Tom Holland gets a lot done in a short amount of time. Although this workout is just 43 minutes long it packs a punch: it's fast-paced and Tom keeps you moving the entire time. Furthermore the workout is filmed in "real" time so there are no edits no breaks. This is a circuit workout with Tom alternating free-form cardio intervals (you can do whatever you want here: march jog jumping jacks grapevines etc.) with strength segments.
