"Start with two days for two to three weeks, then add a third day," says Davis*.*"Ideally, you should strength train three to five days per week, but work your way up—starting off at five days a week might shock your body." Here's a comprehensive three-day-per-week plan to get you started. Aim to complete 20-minute sessions, then gradually add on time in ten-minute increments until you're working for 45 to 60 minutes, suggests Davis.
Complete the exercises in each workout as Straight Sets. For example, you'll do one set of leg presses, rest for 30 seconds, do a second set, rest, do the third set. Then, move on to the next exercise. You'll complete all movements in both workouts this way. Complete 12 reps of all movements for 3 sets each, and rest for 30 seconds in between each set. Choose a weight load where the last two reps of every set are extra hard, where you wouldn't be able to do a 13th rep. You may find that you increase the weight load for each set while keeping the 12 reps for all three sets.
