This quick workout incorporates a resistance band, one of the least expensive pieces of fitness equipment available, to help intensify strength moves beyond what you'd get using just your body.
Michael Schiemer of Frugal Fitness recommends going through this circuit three times. You'll need a resistance band, a Swiss ball, and a 10-15 lb dumbbell.
Resistance band biceps curls: 20 reps
Resistance band shoulder presses: 12 reps
Alternating bodyweight lunges: 40 reps (20 on each leg)
Triceps dips: As many reps as you can do with perfect form
Swiss-ball crunches holding 10-15 lb dumbbell straight up to ceiling the whole time: 15-20 reps
Plank: 30 seconds
