1. Pace
Draw out the positive phase of each exercise (lifting or pushing) for 4 seconds, and the negative phase (lowering or resisting the weight) for 6 seconds. Do each move without stopping for 2 minutes, but if your muscles give out sooner, rest for a few seconds and continue for the remaining time.
2. Weight
Even small dumbbells can get very heavy when you're lifting and lowering so deliberately. Start with 3- or 5-pound weights in the moves that call for them.
3. Mindfulness
Concentrate on the muscle you're working to ensure you're taking it through the full range of motion.
4. Posture
Practice “exaggerated perfect posture,” says Mincieli. For most moves, this means abs tight, shoulders back, and chest high.
5. Breathing
To help maintain your rhythm, exhale during the positive phase and inhale during the negative. Don't hold your breath — this can cause your heart rate and blood pressure to spike, leading to lightheadedness and even fainting.
