►Notes: 1. Start slowly and build gradually. Give yourself plenty of time to warm up and relax through easy walking or gentle stretching exercises. 2. Short exercises several times a day are more suitable for your schedule than a 30-minute exercise. 3. Listen to your body. If you feel pain, shortness of breath, dizziness or nausea, take a break. You may be too hard. In conclusion, people with high blood pressure, stroke, vertebral fusion, excessive obesity, retinal detachment or pregnancy should consult a doctor before the weightlifting bed.
