When headed to the gym or even out for a run, it is best to be prepared. The gym can overwhelm you with choices and without a plan in hand you might wander willy-nilly from machine to machine squandering your time and not give yourself a thorough workout.
So print out a cardio plan if you just want to work aerobically, and this way you will have a plan to follow. If you are going to do some strength training, plan your workout ahead of time. When you are sitting down with a piece of paper listing out exercises, it is easier to see if an area is not getting worked or where you can do super-efficient compound moves or what stretches you can fit in during your rest times.
If you’re headed out for run, decide if you are going long and slow for an endurance workout, for an interval run with sprints and recovery time, or for a short tempo run where you push yourself to go a little past your comfort speed and maintain that slightly quicker pace.
It is great to have a plan, and even better to stick with it. Use my downloadable fitness journal to not only keep track of your workouts, but to plan them as well.
