If you’re hitting a plateau on your lifts do a quick check of your rest periods. In between your heavy, compound lifts (i.e. squats, presses, deadlifts, etc…) aim to rest for 3-5 minutes. Use your phone’s stopwatch or some other device to track the actual time between sets. Often novices will feel ready to lift again after 60 seconds and end up missing reps on their next set. Another technique you could use would be to rest for the duration of a song if you don’t want to use a stopwatch (songs are usually 3 minutes in length). Don’t try and turn the strength session into a conditioning workout!
