Aerobics is exercising until you achieve your “maximum heart rate” (MHR) and then maintaining your MHR for 20-30 minutes. Your MHR is 220 minus your age. Doing this three or four times a week can greatly improve your health.
“The Lord will fulfill his purpose for me; Your steadfast love, O Lord, endures forever.” Psalm 138:8 NLT
In this verse David found his spiritual MHR with some worship aerobics. God refreshed him with a sense of purpose for living and renewed David’s awareness of how much God loved him. Watch and do what David did.
First, he sang praise (Psalm 138:1). The root word for praise is hand. The word for hand is ‘yad’ and the word for praise if ‘yadah.’ He thrust his hands into the air in praise to his Lord! Combined with singing out loud, this is good exercise and also good worship when directed toward your Lord.
Second, he bowed down (Psalm 138:2). The picture here is going from a standing position to laying on the floor face down. This physical act demonstrates his total submission of mind, will, emotions, and body to the Father. For some of us, we might get down there and not be able to get back up!
Third, he called (Psalm 138:3). He cried out in desperation. If thugs attached you in a dark alley, your cry for help would be ‘life or death’ intense! “Shout to the Lord, all the earth; break out in praise and sing for joy!” (Psalm 98:4). Try shouting praises to your Creator as your drive your car instead of insults to other drivers. God increased David’s strength of soul when he did this.
Fourth, he heard (Psalm 138:4). If you want to get someone’s attention, whisper. God usually speaks in a still, quiet voice. “Be still and know that I am God” (Psalm 46:10). This is a focused listening that requires our greatest concentration. Meditate on a Scripture verse or the death and resurrection of Jesus Christ. My wife tells me I don’t have a hearing problem, I have a listening problem.
“Physical training is good, but training for godliness is much better…” 1 Timothy 4:8a NLT
Our Father, thank-you that even if physical training becomes more difficult, we can continue to excel in training for godliness.
