Lift heavier weights – don’t neglect your technique, only go as heavy as you can to maintain correct form for your designated rep range. Using a -2 or -1 rep buffer on your sets is a safe and effective way to ensure you don’t neglect technique for numbers.
Slow down – experimenting with different tempos will make an exercise harder by extending the time under tension. This will force your body to get stronger and the pay off will be quicker aesthetic results.
Shorten your rests – reducing the time between sets will make the next exercise harder to perform and the overall workout more intense. This is an excellent way to burn more calories and achieve a cardiovascular response from the workout.
