It’s important to know a few fundamental principles of strength training:
- Resistance: You have to apply an appropriate resistance to build muscle. The amount of resistance should be above what one is accustomed to in everyday life. Add this resistance by using weight machines, free weights, cable machines, various weighted tools or even your own bodyweight.
- Balance: Make sure to work the entire musculoskeletal system, to avoid postural and strength imbalances and injury. Work several muscle groups at once when possible.
- Rest: Rest between sets of exercise for about 60-90 seconds giving your muscles a chance to recover before you attempt the next set. Also, rest 48 hours between bouts of weight training if you are sore.
