1) Rest. Do you feel tired frequently? Are you losing motivation to get into the gym? If you are pushing yourself too hard and not seeing the changes you want, try increasing your calories for about a week and lessen the amount of activity you’re doing.
2) Limit your stress. Stress is stress. Whether this is due to a relationship issue, stress at work or stress being placed on your body from lifting, your body does not recognize the difference it is just aware that it needs time off. Although many of us will have SOME sort of stress floating around our lives, there are definitely ways to cope with it.
3) Start tracking your rest periods. Do you often find yourself on your phone in between sets or chatting with people in the gym? Start giving yourself less rest in between sets to give yourself a more intense workout (keeping your heart rate up the entire workout).
4) Change up your program. Have you been doing a full body workout for a few weeks now? Maybe try an individual body part split or an upper/lower body split.
5) Switch up your training style. If you always use dumbbells, try adding in barbells or kettle bells. If you have only used machines in the past, try some functional movement patterns.
It’s important to give yourself time to adapt to the new changes that you’re providing for your body. Don’t get discouraged. Stick with the plan and be patient!
