Monday night and I decided I would up my circuits from 45 minutes to 1 hour.  It meant 8 repetitions of 10 exerises, 30:15 secs work:rest ratio.  A mixture of bodyweight and 12kg kettlebell exercises.

Here are the exercises I did tonight (reps) & (HR):

JUMPING JACKS (33) (121)
SQUAT JUMPS (21) (133)
PRESS UPS (20) (117)
DOUBLE ARM SWING (17) (137)
ALTERNATING LUNGES (17) (129)
DOUBLE ARM ROW (15) (130)
TORSO CIRCLES (20) (123)
PLANK WALK UP (10) (116)
SQUAT FIGURE 8 (20) (123)
MOUNTAIN CLIMBERS (38) (122)

It was pretty tough going at points, especially the Plank Walk Ups and the Double Arm Row, but worth it.  .

Circuits: 1 hour, 10 exercises, 8 x 30:15, Calories: 526.
Ave HR: 125 (66%), Max HR: 150 (79%).
